If the unemployment withholding is on line 25b it was factored in. The difference is $1,800. That is probably for the Stimulus payment for Single, 1200 for the first one and 600 for the second one. Did you have an amount on 1040 line 30 for the Recovery rebate credit? Line 30 is only if you didn't get it or qualify for more.
Did you enter the Stimulus payments you got?
