Same problem on Form 2210 Part III Line 10a. TurboTax is not using the info from Form 2210 Schedule A1 line 27a, but is using line 27 information for Line 10b,c,d.
Also the data in Form 2210 Part III Line 11 b & c are incorrect & should be swapped. i.e. Data in Line 11b should be in Line 11c & Data in Line 11c should be in line 11b.
