After you file

Thank you xmasbaby0 for your previous suggestion that I do not amend my 2020 return and allow the IRS time to revise my return, reversing the refunded excess advance premium tax credit; however today I attempted to "Get a Refund Status" under "Where's my Refund?" resulting in a "Cannot provide any information about my refund" and that I should "verify your filing date."  What should I take this to mean.  Granted, I could not fill in the expected refund since I filed 2020 with my owing the IRS but entering the revised (refunded to me) amount resulted in the same "verify your filing date."   Previous results throughout 2021 stated that IRS was "still processing my return."    Am I at the point where I can conclude that they will not be revising my return within the IRS and should finally Amend my Return?  I will likely be owing money on my 2021 return while still being owed a substantial refund from my 2020 adjustment.   Do you know if the IRS is still processing/correcting 2020 returns?  Any insight will be greatly appreciated.
