After you file

@Demo3 - just so you are aware as you wade through this very frustrating situation, 'forever' is your 2020 tax return.   Anyone missing a stimulus payment will reconcile it on the 2020 return. There is no separate filing required; the result will increase your refund (or reduce what you owe).  Some think it's going to be a year and out it on the 2021 tax return, but that is not true.  Any stimulus (called the Recovery Rebate) due is on Line 30 of the 2020 tax return

 

hope for the best
