So basically I entered that I prepaid i.e. $10k in estimated tax payments, but it turned out that I was wrong and transferred only $7k so I have to pay them back $2k + penaltis (I know exact $ value to pay). This year I get e refund for taxes. Should I claim refund and then pay them back via IRS website or is there some way to include that penalty value in turbotax and have it automatically recalculate my tax situation and pay the remaining balance?
