After you file

21 days is aggressive in a normal tax year, but this year has been anything but normal.   The IRS is seriously backlogged due to ongoing Congressional changes in the tax law, lots of extra stimulus filings, and a few million unprocessed 2019 returns left over from the COVID shutdown.  Contacting the IRS will not help, and it has implored taxpayers not to call.  Lots of other folks are still waiting, so please continue to be patient.  Also see:
