TurboTax finally updated Form 2210 for 2020, but incorrectly tried to use column (b) for lines 20-26 (Part IV) for calendar year filers. Please fix this bug.

Column (b) should not be used, but calculations show up for lines 20-24 (and not lines 25-26), which causes an incorrect value in column (c) of line 20 (Part IV, Form 2210).
