My husband has 2 1095-A forms with different policy numbers. One for 2 months and one for the rest of the year. How do I enter both? It only lets me enter one.

Combine them into one form. 

On the screen Here's what we have for your 1095-As at the bottom left corner of the box showing the policy that was already entered click on link labeled Add another

You can enter more than one 1095-A in TurboTax if members of your household have received individual forms, or if you received more than one:

Here's how to enter multiple 1095-As in TurboTax:

1. Open or continue your return.
2. Navigate to the 1095-A section:
   • TurboTax Online/Mobile: Go to 1095-A.
   • TurboTax Desktop: Search for 1095-a, then select the Jump to link.
3. Answer Yes and enter your 1095-A info on the next screen.
   1. We don't need all the info from your 1095-A. We'll only ask about the info that affects your return.
4. After you finish, you can click add another.
