Deducting health insurance costs while self employed

I am self employed, and bought health insurance through my state marketplace.  I received a 1095-A.  However I also read I can deduct my payments from my self employment income.  Can I deduct the portion I paid in my Sched. SE?  Also, when I entered my 1095-A, it lists $1,500 needing to be repaid for the tax credit.  Since that is essentially health insurance premiums that I need to pay back, do I get to add that $1,500 to my deduction for health insurance premiums?
