Get your taxes done using TurboTax

Based in the information given to me in my previous inquiry (referenced above), it seems that Turbo Tax does not properly handle the self employed insurance deduction when AGI is "on the edge" of a subsidy.  Can you review my previous question and advise me if there is a better way to handle this?  I still don't understand how TT calculated the lower amount indicated on the bottom of the line 29 worksheet.
