Do I need to print my forms and send them into the feds even if I e-filed? My parents have to with theirs, and I don't remember if it stated the same thing for me.

No - If your return was e-filed you don't have to mail anything in.

Your parents may have to mail in brokerage statements that they summarized on their return, or something else.  Chances are their return is more complicated than yours!
