STILL WAITING FOR STATUS OF 2020 RETURN

[wwamp98]

I filed my 2020 federal taxes on Feb 23, 2021.  I still have not gotten any information since it was accepted.  I have been trying to find out what has happened.  they sent me a notice on 6/9/2021 and I corrected the error and sent the form back.  Should i. resend the form in case they lost it.  I have been calling with no success since last May with no results or ability to talk to anyone yet.  I realized they are backed up.  any suggestions.  Thank You.
