I had this same cenario happen a few years ago and am now experiencing it again in versions 2021 & 2022. I have tried the steps you posted here but it has not fixed the problem. I have called 2 times and have 2 support cases opened and have uploaded 4 sample files and cannot get a resolution. We are in crunch time with tax return preparation staring us down. We have up to 20 clients that send Accountant's copies each year. Please find a solution ASAP.
