Deductions & credits

Did you check the box for self employment when you entered the 1095A?  

You only enter it from the 1095-A. When you enter the 1095A there should be a box to check for self employment. If you enter the 1095-A and select the "Self-employed and bought a Marketplace plan" box, it will automatically include those premiums in the SE Health Insurance section. So you shouldn't enter it again on schedule C.
