After you file

@Lee Foote You were not "over charged"  --- you had some sort of mistake on your tax return that was corrected by the IRS.    The IRS will send you a letter that explains why you now owe tax.  Did you make a mistake with the 3rd EIP payment?   That has been very common this year.   People forgot to enter that they already received the $1400 per person stimulus check last year and it put the $1400 on line 30 of their tax return again.   You cannot get the $1400 twice.  So the IRS removes it----that could be why you owe now.
