On Form 2210, when I checkmark Part II D, I get error message and it won't let me e-file my return. The error cited is that sum of four columns of Tax Withheld Smart worksheet does not add up to the total Fed tax withheld. I have checked several times that sum of four columns on worksheet adds up to the total Fed Tax withheld. My withholding of taxes was very high in the first quarter, accordingly the penalty is significantly reduced by check marking the Part II D, as opposed to using equal average withholding for each quarter (appears to be Turbotax default computation).
