Turbo Tax incorrectly enters the first three periods of Schedule, causing a penalty when one isn't due. Are they going to fix this?

In Schedule AI on Form 2210, you enter your adjusted gross income (line 1) and itemized deductions (line 4) for each period.

Are you saying that TurboTax mis-entered one of your inputs, or that it made a calculation error on the form?

If so, on which lines?

Schedule AI is correct through line 13. Turbo Tax calculates the tax wrong on line 14 for column (a), (b), and (c). Column (d) is correct. Form 2210 is correct through line 9, but when Schedule AI numbers come over to Part III, I end up paying a penalty on line 19 due to the incorrect tax calculation.

I have read in forums that this is a common known problem. It would cost me more in postage to manually do my taxes with the correct tax calculation and mail them than my $8 penalty, but I would prefer my taxes to be correct.

As you are probably aware, we in the Community cannot see your private tax data nor the screen you are on, so it would really help a lot if you would tell us exactly what you think is wrong.

Yes, there were discussions two months ago about wishing to override line 14, but that was addressed, so I have no ideas what you mean that TurboTax is calculating the tax wrong on line 14.

Please let us know some more detail.
