In my copy of TurboTax Desktop 2021, TurboTax is calculating a penalty for late payment, on Form 2210 Part III - Penalty computation lines 10 to 19. However, the amount of estimated tax payments calculated as paid by July 15th is only taking into account the 1st quarter of 2021, ignoring payments made during the 2nd quarter of 2021.
Also, that part of the form itself seems to have been copied from 2020 and not updated, since it only has columns figured for payment dates column (a) 7/15/20, column (b) blank, column (c) 9/15/20, column (d) 1/15/21!
