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?
Returns filed in 2023 need to use the IPPIN that was issued in 2023, so you need the one that was issued most recently, not the one that was issued for the original tax year.
