Form 2210 Underpayment Penalty

[JHolroyd]

I keep encountering an error with my taxes “Form 2210: Line D Withholding. The sum of the four columns is not equal to your total withholding of $XXXX for the year.” However, the numbers I have entered do add up to my total withholding, and the form is not reflecting in the second column what I have entered. I have re-entered correctly about 5 times and every time it flags this as an error and asks me to fix. I have even tried just giving up on annualizing and just paying the penalty because I am so irritated at this point and even that does not seem to work as just keeps taking my back to the same error. At this point I have wasted hours on this.

It looks like a programming error on the part of TurboTax. Happened to me, too. I looked at the error report which had an image of the worksheet and noted that the worksheet had four columns for withholding payments in 2020 when there should only be three periods. I suspect that you filled out the information for Form 2210 before the 2/26/21 TurboTax update. If you did, you provided information for four periods. After the update TurboTax combined the first two periods into one period, but it appears that TurboTax left a "ghost" of you previous second period input in the worksheet and, presto, when they add all four columns in the worksheet it produces an error. I fixed it by zeroing out the 2nd column in the worksheet in the error report.
While that solved that error, TurboTax is currently not filling out Part IV of Form 2210 correctly. I will solve that by switching to the H&R Block tax software next year. This type of error is inexcusable two months into the tax season.
