tried "0" for AGI but still was rejected. The rejecting reason is this...
IND-031-04 - The primary taxpayer's AGI or Self-select PIN from last year does not match IRS records. So, apparently this self-select PIN could be the issue. I did 2020 return by paper/ink and mailed it. Certainly did not involved a PIN. Possibly the year before my CPA had a PIN for his efile then. It seems I have no choice but to mail in the return.
