Business & farm

The problem is not with saving a complete copy of my returns for my records. The issue is specifically after I've e-filed my Federal Business returns, it takes you to a screen that says "even though you e-filed there are still some paper forms you may need to print to ensure your return is complete." You are to click on the button to print forms, but when I select it, it says that there is an error.  I've already tried downloaded a different pdf reader and that didn't solve the issue. Now I don't know what forms I still need to send in and where to send them?
