[2] At the 2018–19 Grand Prix Final, she landed the maximum eight triple jumps cleanly in the free skate allowed under the Zayak rule, becoming the third woman to do so after Japanese Rika Kihira and American Mirai Nagasu.

[3] In the final event of the 2018–19 season, the 2019 World Team Trophy, she successfully landed all twelve jumps cleanly, becoming the first woman to accomplish this feat in an official international competition.

Tuktamysheva's career is notable for its consistency and longevity, especially in contrast with the young ages and high turnover of elite Russian women's skaters in her era.

In July 2020, Tuktamysheva received her diploma from the Lesgaft National State University of Physical Education, Sport and Health in Saint Petersburg.

[8] Since her family could not afford to move to a big city, she remained in Glazov, continuing to train under Veretennikova, but regularly visited Mishin in Saint Petersburg, where she lived in a dormitory.

[33][34] Tuktamysheva debuted on the senior Grand Prix circuit at Skate Canada International,[35] where she won the gold medal with a combined personal best score of 177.38 points, becoming the youngest champion in the event since Tracey Wainman in 1981.

After taking the bronze medal at the 2013 Golden Spin of Zagreb behind Miki Ando, Tuktamysheva competed as the defending champion at the 2014 Russian Championships.

[49][50] The results qualified her to the Grand Prix Final, which she won with a new personal best combined total of 203.58, ahead of Radionova and American Ashley Wagner.

She subsequently won the 2015 European Championship by a slim margin of 0.86, finishing second in the short program and first in the free skate, posting personal bests in both segments.

[56] She decisively won the event, earning 16.76 points over silver medalist Satoko Miyahara, becoming the third Russian woman to win the World Championships (after Maria Butyrskaya in 1999 and Irina Slutskaya in 2002 and 2005).

[citation needed] Tuktamysheva began her season by placing third in the individual competition of the Japan Open before winning the gold medal at the 2015 International Cup of Nice.

Tuktamysheva finished first in the 2015–16 ISU Challenger Series standings after winning gold medals at the 2015 Warsaw Cup and at the 2015 Golden Spin of Zagreb with a season's best score of 201.33 points.

[68] She started her season in September at the 2018 Lombardia Trophy, where she won the gold medal by a margin of over 21 points over the silver medalist, her training mate Sofia Samodurova, after placing first in both the short program and the free skate.

She won the competition by a narrow margin of just 0.26 points over silver medalist Mako Yamashita after a costly fall on her triple Axel in the free skate opened the door for the rest of the field.

[69] In early November, Tuktamysheva competed at her second Grand Prix assignment, 2018 NHK Trophy, where she won the bronze medal behind Japanese skaters Rika Kihira and Satoko Miyahara.

At the Final, Tuktamysheva returned to the podium with a bronze medal, landing all of her elements cleanly except for the triple Axel in her short program, which was judged underrotated.

After several days of deliberation, the Russian Figure Skating Federation's board of coaches named Medvedeva to the team along with Alina Zagitova and Tuktamysheva's training mate Sofia Samodurova.

[76] She initially had a short program from Canadian choreographer Shae-Lynn Bourne to Florence + the Machine's "Drumming Song", but decided to change the music while aiming to retain much of the original choreography before the beginning of the season, instead using Astor Piazzolla's tango "Oblivion".

[77][76] She began her season at the 2019 CS Lombardia Trophy where she placed first in the short program and second in the free skate to earn a second-place finish overall behind Russian teammate Anna Shcherbakova.

Tuktamysheva subsequently returned to the "Drumming Song" music for the short program for her next competition, 2019 CS Finlandia Trophy, where she placed second behind Alena Kostornaia.

[78] Beginning the Grand Prix at 2019 Skate America, Tuktamysheva landed her triple Axel in the short program but made errors on both other jumping passes, as well as receiving low spin levels.

[80] At the 2019 Cup of China, Tuktamysheva fell on the triple Axel in her short program and performed only a double toe loop as the second part of her combination, placing fourth in that segment.

[84] She attempted the quad toe loop in competition for the first time but under-rotated and fell on it, in addition to other jump errors that had her place ninth in that segment but remained in fourth overall.

[85] The oldest ladies' skater in the field, Tuktamysheva was named first alternate for the European and World Championships behind a trio of first-year seniors (Anna Shcherbakova, Alena Kostornaia, and Alexandra Trusova).

[89] In the free skate, she executed two clean triple Axels, one in combination, to win the segment and the competition overall, in what was considered a significant upset victory over both Kostornaia and Alexandra Trusova.

This was the second time, after the United States with Tonya Harding, Nancy Kerrigan, and Kristi Yamaguchi in 1991, that a single country swept the ladies' podium at the World Championships.

At Finlandia, Tuktamysheva cleanly skated her short program to score a new personal best and win the segment ahead of Russian teammates Alena Kostornaia and Kamila Valieva.

[107] On the Grand Prix, Tuktamysheva won the silver medal at the 2021 Skate Canada International behind Valieva and ahead of Kostornaia, in a repeat of the podium at Finlandia.

She climbed to sixth in the free program with a clean skate but ultimately finished seventh overall and fourth of the skaters age-eligible to compete at the 2022 Winter Olympics and the season's remaining ISU Championship events.

At the Russian Championships in December, Tuktamysheva placed second in the short program and fourth in the free skate to finish third overall behind Sofia Akateva and Kamila Valieva.
