I made four timely equal estimated tax payments for 2021. They add up to more than my tax liability for either 2020 or 2021. (My taxable income is less than $150,000.) I completed the "California Carryover Worksheet" and "Tax Payments Worksheet".
Somehow, TurboTax says I owe a $3 penalty, and attaches a "Form 5805" and "5805 Wks II" to my return. On Form 5805, lines 7-12 are empty (there was no underpayment) but a persistent $3 penalty appears in line 13.
The penalty seems to come from "5805 Worksheet II" - line 12 (which shows the $3 penalty) adds up "line 11 in all columns" - but line 11 is all blanks. If I delete any of these forms, they're immediately regenerated. 5805 is supposedly finalized, but the column headings for the Worksheet II Part 1 Payment Due Dates are 7/15/2021, 7/15/2021 (!), 9/15/2021, and 1/15/2022 - Per the CA FTB they should be 4/15/2021, 6/15/2021, 9/15/2021, and 1/18/2022. And it looks like the "Required Installments" are computed incorrectly...
How can I correct this? It isn't material - but it is a worrisome error. Thank you.
