Tony, I wasn't able to reproduce the problem with Line 11 columns b+c being swapped.
But, TT has another error related to this form that may be your issue. In the step by step interview they are giving the wrong dates for tax withheld. TT has the dates for tax withheld incorrect for the 2nd and 3rd payments. They have the withheld dates as 4/16 - 7/15 (3 months) and then 7/16-9/15 (2 months) in the Step by Step interview process but the dates on the actual form are 4/16 - 6/15 (2 months) and then 6/16 - 9/15 (3 months). I think this could give the appearance of being swapped. The dates on the actual form are correct and should be used for the tax withheld calculation. Hope this helps.
