Do I need to mail anything in after completed my taxes online?

I had a regular return.  I already received my refunds.

No.  When you file electronically, unless you are specifically told to mail a form in, you don't need to mail anything in after filing.  And, if you have already received your refunds, then there is nothing you would need to mail in as your returns have been processed.
