Same thing for me. I set up a payment plan with the IRS for 2021 tax year. I sent about 6 payments before I realized it was going to 2018 (which makes no sense because I followed from a letter saying to set up payment for 2021). Ive gotten letters in the mail about overpaying to 2018, but the balance has not been corrected. My balance shows much higher than what I owe. Of course I call the number and not only is there no prompt for this but I cant get through. Has anyone had any help
