Taxes 2022 CP503

My question is that I had been sent a letter saying my taxes could have been hacked. Well then about a month later I received another letter saying I owed these new taxes. I paid them in payment over the course of 6 months and paid off my taxes. So, I need turbo taxes to see if we screwed up. I am a card-carrying top of the status line with you guys for at least 5 yrs. Please send me a response by email or call me you have both. I do have the paperwork if you need to see it.
