Health insurance deduction for S Corp does not match Sch 1 Line 16 amount for 2019. How can that be?

On my 2019 1040, my imputed income for my health insurance ($11,554) from my W-2 (line 14) was data inputted as such when I prepared my return using Turbo Tax.  My health insurance deduction on Schedule 1 line 16 was $2,853.  How come they are not the same?
