I see the same issue I am currently dealing with for my 2021 tax payment. I paid on their website and the amount I paid I can see the history of the payment as well as it was taken from my bank and I still have the confirmation email . My tax person was going to reach out to them for me a month ago with a form to help me clear this up but she is on vac and cant not follow up with her. I have tried calling no luck. I see its suggested to send a letter response I got a month ago from their letter saying I owed with my proof. Is there anything else suggested to send them and where would I send it? I can see my IRS balance has gone up 3 more dollars from interest but would like to handle this asap. I paid it in Feb of 2022 for 2021 taxes and had no clue I had a balance until I got the letter . Also we file jointly so would I need to include his information. Any help is appreciated
