So apparently I can’t ask questions about the previous tax season before this next one so I ask you community, why did the IRS not receive my payment from last year?

For context, I filed my taxes on time for the 2024 tax season. Yes I did make the payment. The app even says I did. But I’m getting letters from the IRS saying they haven’t received a payment. I’m going through some old mail today as I do ant the end of every year and that’s when I found the letters. I can’t even ask a live agent for help until I select a package for this upcoming tax season. Which hasn’t even started yet!
