I filed my 2020 tax return last year on time, it was accepted and done. and yes, I've used the same TurboTax account.
Honestly, the only thing I need is for someone to log into their Turbotax account and try to click on the "Amend 2020 tax online" button to see if they are having the same issue to confirm whether the issue is just me or globally across their system.
Not to disrespect any other answers but I've done my research and I know this is not user issue.
