TT update on 3/3/22 did not fix any of the errors in Form 2210. Still not calculating line 14 (a)-(c) on Form 2210AI correctly and still using the wrong dates in step by step for annualizing withholding. 2021 TT Form 22210 is a piece of junk that TT isn't making any effort to fix and TT 100% accuracy guarantee isn't worth anything so they don't even try.
