I am amending a corporate and personal 2020 and 2021 for a small lawyer S Corp in receipt of ERC funds.  1120S amended E filed no problem. I get rejection notices for the 1040 as the original 1040 needed an IRS PIN for identity theft.  I have those numbers as we E filed the original 1040's.  I've tried running it with those codes, no codes etc.  No luck.  Before I paper file... anyone have this happen?
