Took my refund for past due amount but I've always paid my taxes in full

I paid my 2023 taxes in full. I submitted everything accurately, and double and triple checked it because it was so much. This year, I was only supposed to get $290 back, but I just got a letter saying it was applied to the balance I owe from 2023 taxes!! This is the first I've heard of any conflict in my tax amount - wouldn't they have communicated if I hadn't paid correctly last year, at least with a letter? I can't imagine this is correct.
