I am using TurboTax 2024 Desktop.
I legitimately need to pay a penalty for underlayment of Indiana estimated taxes in 2024. However, it appears that TurboTax is overcalculating the amount of that penalty.
Specifically, Form IT-2210 Row 16 Column A is blank, even though an estimated tax payment was made by April 15, 2024, and that payment is visible is the total estimated taxes paid on Schedule 5 Row 4.
Said another way, the total estimated taxed on Schedule 4 Row 4 is not equal to the total shown on form IT-2210 Row 16, even though all payments were made on time. Columns B, C, and D show the proper amounts, but Row 16 Column A is blank.
This appears to be a bug in the Indiana calculation.
