OK, I mailed a paper copy (didn't appear to have a choice to e-file) of my amended 2020 tax returns in April of 2021. I have called them months after sending it and they used every type of identifying info to look for it and they couldn't find it or show it was received. A few months after that, I mailed a letter along with an unsigned copy of my amended return (for reference) asking them to review it thinking that it would get them to look for my original signed amended return. When I sent the letter, I used UPS and used the tracking number to locate it. They received it a few days later and to this day I have not received any letters from the IRS or any confirmation on their website that it is in their system. Should I resend another signed copy of the amended return and hope they actually review it or do I have to prepare to just cut my losses?? I don't feel like having to make a day of trying to contact the IRS again and be on hold for ever only to be told that they can't find it again!
