How do I change my response to Did I have Affordable Care Act Insurance?

[Vanessa A]

If you had it, you can just enter the form without changing the interview question.  

The ACA/1095-A questions are now found in the deductions and credits section under medical. 

You can get there by typing 1095 in the search box and then click jump to or you can click

Start next to the Affordable Care Act (Form 1095-A) 
Walk through the steps to enter your 1095-A information

If you did not have it, then just skip that question.  The interview questions do not affect your return, they are only there to give you a more guided tax experience based on your specific situation.
