How do I updated form 2210? I keep getting this error: "Form 2210: Line D Withholding. The sum of the four columns is not equal to your total withholding for the year".

I've tried removing and readding my W2 and clicked through the underpayment penality seciton multiple times. I've also tried changing the number on the "check this entry page" to match the number shown. I keep receiving the same error.

It's possible that you have some additional withholding that's not in box 2 of your W-2 - usually excess Medicare withholding. Multiply the amount in box 5 of your W-2 by 1.45%. If the amount in box 6 is higher, you'll need to include the difference on your 2210.
