For Form 2210, Line D Withholding, it says the sum of the 4 columns doesnt equal my withholding, but then it only shows 3 columns. Is there a workaround so I can file?

This seems to be a bug in Turbotax?

I recommend reviewing the input section of the program to ensure you have entered all of the applicable information needed to generate the information on Form 2210 correctly.

To do this, log back into TurboTax and select the Other Tax Situations section. 

1. Select Additional Tax Payments and then select start/revisit to the right of Underpayment Penalties.
2. Proceed to answer the questions until you see the screen titled "Annualized Income Method" and select yes.
3. Answer the questions on the screens as applicable until you see the page titled "Actual Withholding" and select yes.
4. This is the screen where you will need to make the quarterly withholdings which will flow into Form 2210, Part II, Box D.  
5. The quarterly withholdings will be shown in the Tax Withheld Smart Worksheet below this section. You should see the quarterly amounts.  The total from all these boxes should add up to the total withholdings for the year and eliminate the error message you are receiving.
