Even if you have a W-2 from your business you will have either a Schedule C or a K-1 reporting your remaining business activities that identifies you as self-employed. You will be sure to mark the box " I am self-employed and I bought a Marketplace plan" on the screen after you input your 1095-A information and will then be asked to link the form to your self-employed income. Here you will choose the Schedule C or K-1 that is appropriate.
