Do I need to mail anything into the IRS?

[AshleyRose]

Generally, when you e-filing a return you do not need to mail anything in as e-filing was meant to replace the mailing of paperwork. If you e-filed your federal return and were suppose to mail anything in you can find what it is that you need to mail by opening up the PDF version of your tax return, before printing, and you will see an instruction page with what you need to print and mail.
