I filed my 2020 taxes already and my federal was accepted. I received a form 1095-A after I had already submitted. Was that something I needed to add ? How can I fix it?

I already submitted my federal and state return like two weeks ago but received my 1095-A from Health Insurance Marketplace after and I have had no idea what to do. My federal was just accepted. Did I need that 1095-A added ? What can I do now to solve that?
