The tax calculation on form 2210 AI line 14 in columns (a), (b) and (c) is incorrect. This is an annualized calculation and the amount for gross income (including qualified dividends and capital gains) has been annualized. But when doing the tax calculation, the 15% capital gains tax rate should be applied against an annualized capital gain and qualified dividends amount. However, Turbotax is only annualizing the qualified dividends amount and not the capital gain amount. Too much of the annualized gross income amount is getting a regular tax rate and not the capital gain tax rate.
