To enter the 1095-A form:

If you already filed your return you need to amend to make any changes.

Here's how you amend your return:

1. Sign in to your account.
2. Scroll down to Your tax return & documents , select 2019 and then Amend (change) return. 
3. Select Amend using TurboTax Online.
4. Follow the instructions, your refund or tax due will change to 0. This is normal on amended returns.

Amended return can't be e-file, you need to print it and mail it in.
