Please see this answer from LindaA. Although it is from a previous year, the information still applies.
You'll need to indicate how long you were covered by either plan in 2016 (in your case, all year) and enter information from the Form 1095-A for your marketplace plan.
Go to the Health Insurance section and indicate that you had coverage all year (since you had marketplace coverage for 6 months and employer-sponsored coverage for the other 6 months). Continue through the interview and answer the marketplace questions:
- Were you enrolled in any of these less common plans in 2016? Yes
- What type of plan were you enrolled in? Obamacare plan (1095-A)
- Do you have a 1095-A form to enter for your Obamacare plan? Yes
Next, enter the information from your Form 1095-A (Health Insurance Marketplace Statement), then continue answering the questions in the Health Insurance section. When you're finished, TurboTax will display That's all we need on your 2016 coverage.
Note: You may receive a Form 1095-C for your employer-sponsored coverage, but this form isn't needed to file your tax return. Just be sure to store it with your records.
