Deductions & credits

 

look at schedule A, if you elected to deduct foreign taxes they would show up on line 6 and are in addition to the $10K standard limitation.

could you have paid state taxes in 2021 or applied a state tax overpayment from 2020 to 2021? are they on your list? 

 

that number had to come from something you entered.  contact support for help.
