No, if your e-file was accepted you do not need to mail in anything. Keep a copy of your return and your documents for your own records.
Note: Every year, before mid-October, print a copy of your current year tax return and save it as a tax file and pdf, too. That way you will have it when you need it for school, a loan, next year’s tax return, etc. without going through a lot of aggravation (and expense) to get it.
