The error that you are getting is due to having Form 1095-A in your return and not completing Form 8962 completely on your return. The error could be because you started entering something for Form 1095-A or accidentally selected a box for it. If this happened the program would have started calculating Form 8962.
Since she didn't receive insurance through the marketplace, you don't need anything completed for either Form 1095-A or Form 8962. Follow the instructions from NicolleR1 and delete Forms 1095-A and Form 8962 from the return, if the program started them.
If this doesn't clear your error, you could also try troubleshooting your web browser. Turn off any pop-up blockers, use a different web browser, delete your browser cookies.
