Version R!9, just released within the past day or two, has introduced a new problem with the calculations on Form 2210 Part IV lines 20 through 26. An overpayment shown on column (a) line 26 is not propagating to column (c) line 20, resulting in an incorrect underpayment being shown on column (c) line 25 and on column (d) line 25. There is, in fact no underpayment. Overriding either column (b) line 26 or column (c) line 20 to apply the overpayment from column (a) line 26 results in a correct calculations on columns (c) and (d) lines 20 through 26.
This is a problem on my own tax return where I must annualize income due to a large portion of my income occurring in Q4, requiring me to file Forms 2210 and Schedule AI (Form 2210). Somehow TurboTax is doing a correct calculation on the Underpayment Penalty Worksheet and coming up with $0 of penalty on Form 2210 line 27, but that's contradictory to the (incorrect) underpayment shown on columns (c) and (d) line 25.
I've uploaded a stripped-down test file to demonstrate the problem, Token 260848.
@Katie_B , I'm mentioning you to bring this to your attention so that you can pass it along to Product Quality.
