Other notes:
1) make sure you have a record of that amount being removed from whatever account you used to actually pay it.....on or near that date.
2) Sounds like it was an extension payment. Since it was part of an extension, did you eventually file your final tax forms at a later date...before 15 oct of 2024? And include that payment as having been made as a part of your final tax return? (assuming you did pay it back in April).
Certainly, talking with an IRS agent now is the best way to go. to see what happened, and if the~30k payment you made back in April, was properly applied to the correct tax year.
