As of 3/1/2021, Form 2210 Part IV still has an error in that the first period's estimated tax payment and withholding amount is not added to the other period's estimated tax payments and withholding in determining whether a penalty is to be imposed. This error was brought to TT's attention yesterday but it has not yet been resolved and an update issued. If you have filed Form 2210 since it became available on 2/26/2021 and a penalty was imposed, it is suggested that you check to see if the penalty is reduced or eliminated after this error has been corrected and the update released.
Check your return, if Part IV shows an overpayment on Line 26 in column a and does not show this same amount in Line 26 in column b and Line 20 in column c, your first period's overpayment has not been taken into account if figuring any penalty.
