What if I had 2 insurances in 2019

It doesn't matter how many you have. They all count towards meeting your obligation to be covered. If one was a arketplace plan for part of the year and the other was through work for part of the year, you just need to enter them separately.

The information in your W-2 will handle the work insurance. There should be a code indicating coverage in Box 14. Enter your ACA information from the Marketplace using the following steps.

The steps of reporting are as follows:

Did you all have health insurance coverage in 2019?   

Was anyone enrolled in any of these less common plans in 2019?  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

The program will prompt you to enter the 1095-A for the months applicable. You need enter nothing for the insurance through work.
