In the short program at the 2020 Rostelecom Cup Trusova fell on a downgraded triple Axel and, as a result, placed third behind Kostornaia and Elizaveta Tuktamysheva with a score of 70.81 which was her lowest international result since September 2017. She encountered similar problems in the free skate, falling four times and receiving negative grades of execution on two other jumping passes. Her final score of 198.93 saw her drop down to fourth place, unprecedented for Trusova in international competition and her first off-podium finish since the 2017 Russian Junior Championships.
