Did you not get the 3rd Stimulus payment? Or qualify for more? LOOK at your form 1040 Line 30 ...it is ONLY if you didn't get the full amount or qualify for more. The IRS shows they already sent it to you so they changed your return. There is nothing you can do about the balance due ... pay it ASAP.
Then ... Double check your bank statements and Check your IRS account (both accounts if married) to see if you indeed did get the advance payment. You get either the advance or the credit but not both.
