Update from 2/24/22 didn't fix all of the problems with Form 2210. Filed my return after this update eliminated underpayment penalty, but IRS rejected because of additional issues with Form 2210 in those cases that income and withholding are annualized. TT indicated that an updated version of Form 2210 will be issued on 2/25/22 to correct the additional problems so my return can be accepted. Crossing my fingers that they finally fix all the issues with this form, but I'm skeptical based on their poor performance to date.
