Anyone else dealing with this?

I mailed in 3 separate filings:

2021 amended return

2022 return 

2024 return

On January 31 I sent them thought certified mail and as of today still no updates at all, nothing on transcripts or anything. I called the IRS and the rep said my 2022 and 2024 should’ve shown up by now but they don’t see anything in the system.

They told me to re-mail everything, so I sent them again on March 26 and they got delivered March 31.

Still nothing showing yet.

Is anyone else dealing with this with paper filings? How long did it take before yours at least showed up?
