They overpaid her for disability payments. The letter from the IRS shows TY2016 repayments of 11,528.00. It's just not listed on box 4 of the Form I have. But if I enter that amount in box 4 I get the same tax due that the IRS is requesting. Just didn't know if I should enter the amount in box 4 since it's technically not on the form I'm entering or if I should just enter as I have it and let them make the adjustment.
