After you file

Appreciate your reply.  I still don’t understand the future dates for the 570 and 571 codes.  Checked transcript on 3-23-2021, so why wasn’t 570 “hold” code dated 3-23-2021 or earlier?  And how can IRS know a week later that a 4-12-2021 571 release hold code will be justified, way back on 3-23-2021?  Dates simply make no sense.  Suspect a mismatch problem:  Never received a 1099-G for my Calif state tax refund, so used Turbotax’s “no 1099-G” option to report state refund amount.  Not taxable for 2020 federal, though, since for 2019 I took standard deduction for federal.  None of the other situations you mentioned apply, I am a single, retired filer with no dependents, so my tax situation is not complicated.
