Problem is not fixed and trying to get TT support to investigate has proven worthless for me and others. Note that another employee tax expert (BillM223) in another thread confirmed that there was in fact a problem with line 14 calculation, so please get your stories straight and fix the problems with 2021 TT Form 2210AI.

Also the step by step for annulized withholding in underpayment section is also showing wrong dates as of latest update. Perhaps, it you actually looked at the multiple comments in multiple threads discussing 2021 Form 2210 errors even after the latest update you would understand that problems have not been fixed, with the single exception that the error in transferring info from line 27 in Form 2210AI to line 10 (a) has been fixed. Many people have gone ahead and filed even though Form 2210 is wrong, either because the errors weren't sufficient to create an under payment penalty or they just gave up and paid because they were tired of dealing with TT inability to fix the problems.
