The amount of your self-employed health insurance deduction is not permitted to exceed the premiums paid minus any net Premium Tax Credits you received. When you proceed through the section where you enter your Form 1095-A, you'll mark the box to indicate that you were self-employed and bought a Marketplace plan. TurboTax will then do an iterative calculation to produce a combination of self-employed health insurance deduction and PTC that is permissible.
