Did you use the 2019 Turbo Tax to file 2019 last year back in 2020? Maybe you are still seeing Accepted for your 2019 return?
Anyway, I wouldn't worry about what happened with your 2020 return done on the 2019 software. It probably didn't go anywhere. Sounds like your real 2020 return done right on the 2020 program did get efiled and Accepted. I think that's all that matters.
