As I noted earlier in this forum (and in others reporting similar issue), there is a way to get 2021 TT to correctly calculate line 14 (a)-(c) if you have any long term capital gains in the first three periods. Simply enter the combined total of cumulative CG/QD into the inputs for QD and enter zeros in the LT CG boxes. TT will then properly scale the total CG/QD by the respective period factors and produce the correct values in line 14 (a)-(c) that TT uses to determine whether an underpayment has occurred. The specific breakdown between CG and QD is never shown in either Form 2210 or Form 2210AI that get filed when forms are printed and the IRS accepted a return that was e-filed with this tweak. Use of this option should be considered if TT calculates that an underpayment is due in order to eliminate or reduce a penalty that TT has over estimated because of their failure to properly implement the IRS requirements in Form 2210AI.
Since it is less than 2 weeks until 4/15/22 due date, TT will likely never fix their screwups in 2021 Forms 2210 and 2210AI to perform the proper calculation (s) per IRS requirements, even though they did it correctly in prior years, so consider using the workaround to get the correct result the IRS wants.
