Form 1095-A - Ownership of Form
1

Taxpayers should enter all Forms 1095-A for their tax family; however, as the ownership of each individual Form 1095-A does not affect the calculations in the return, the TaxAct® program does not request ownership information on the Q&A interview screens. 

The one exception is if you are using the alternative calculation.  If you are completing the screens for that calculation, you will be prompted for the ownership of the form you are currently entering.
