[1][2] The ISU Figure Skating Media Guide 2024/25 lists Petrosian's name among the "firsts"[3] but add a note these accomplishments occurred in domestic competition.

[10] Her final competition of the season was the Moscow Championships where she won the silver medal behind Akateva with a total score of 199.89.

[11] Petrosian would have been eligible to compete in the 2020–21 ISU Junior Grand Prix circuit; however, the series was canceled due to the global COVID-19 pandemic.

[15] In March, she competed at the Russian Cup final in Moscow where she won the bronze medal behind Akateva and Sofia Samodelkina with a total score of 204.22.

She placed third in both the short program and the free skate to take the bronze medal overall behind Russian compatriots Veronika Zhilina and Sofia Muravieva, with a total score of 201.21.

[19] In the free skate, she once again attempted the quadruple toe loop, but she touched her hands on the ice on the landing, but she still won the gold medal overall with a total score of 210.57.

[20][21] Due to the COVID-19 pandemic, the International Skating Union announced an alternate qualifying procedure for the 2021–22 Junior Grand Prix Final which allowed each winner of the Junior Grand Prix events to qualify for the final as opposed to evaluating the results of each skater over two events.

However, as of 2023 Valieva has been stripped of her National titles due to doping charges, meaning Petrosian retroactively took third place.

At the 2023 Channel One Trophy Petrosian was assigned to the team entitled the “Red Machine” which was captained by Alina Zagitova.

In the short program she landed all jumps including her triple axel cleanly and scored a new personal best of 85.62 points.

Later, Petrosian also won the 2025 Russian Grand Prix Final despite popping her intended triple axel.
