Do HSA contributions get considered for 1040 line 10a? As I understand it they are but they are not being considered in Turbotax calculation. 8889 is generated though.

I contributed up to my HSA limit in 2020, and Turbotax is generating Form 8889 with the right information. However when calculating my adjustments to income it is not including those contributions in form 1040 line 10a (I have no other adjustments here, so the line is completely empty).

I am using standard deduction otherwise in line 12. Did I misunderstand whether HSA contribututions are considered in line 10a or did I miss something when I gave turbotax the information?
