In 2023 TTax said I owed a $243 penalty. I filed in late Feb and paid it. Got a U.S. Treasury check back for $243. Anyone else have this issue? How do we get TT to fix?

I made 4 quarterly estimated tax payments during the year, but underpaid by a few thousand. I filed in late Feb paying both what I owed and the penalty TT said I owed ($243). In April, I got a check back from the U.S. Treasury for $243 - the exact penalty amount. That infers I did not have the penalty that TT said I had. Seems to me as long as you make 4 quarterly payments, and file and pay what you owe prior to April 15th, you are good to go. Can anyone ask a TT rep if that is the case? Thanks!
