If you've already e-filed your return, then, no, you don't need
to send any forms in to the IRS unless TurboTax specifically told you to when you e-filed.
Please see the
TurboTax FAQ "Do I need
to mail anything after I've e-filed?" below.

However, if you haven't efiled yet, or you're planning to paper-file your return, please reply back in the comment box with what your situation is.
