I can't imagine why the amount on Schedule 1 line 36 would not be subtracted from the amount on Form 1040 line 6 to produce the amount on line 7.
I suggest looking at the TurboTax's 1040 Worksheet where all of the calculations are actually done, with the results simply transferring to the corresponding lines on Form 1040.. If you are using the online version, you can view this by clicking Tax Tools ->Tools -> View Tax Summary -> Preview my 1040, otherwise view it in forms mode.
