There appear to be two unresolved issues with the updated forms 2210/2210AI in the Feb 17 update when Part II box C is checked (annualized income installment method):
1) Form 2210, Part III, Line 10, column (a): incorrect transfer of amount from Schedule AI, line 27, column (a) (some 10x larger amount that doesn't seem to correspond to any field in 2210AI is entered). The amounts in the other columns are transferred correctly.
2) Form 2210AI, Part I, Line 7: amount from line 12b from Form 1040 is not added to standard deduction
In both cases, overriding the field and entering the correct value manually leads to the correct overall computation (and no underpayment penalty in my case, whereas with the errors TT computes a large penalty)
