I filed electronically but I still have to print & snail-mail all these pages? Dozens of pages of both federal & state??

Since the tax returns were e-filed there is nothing you need to mail to either the IRS or to your State.  That is the whole reason for filing electronically.

Why do you think you have to mail it?  If you e-filed your tax return and it was accepted, it was all done electronically.  You do not mail the return.   You can print it for your own records if you want to.

Did you e-file?  Did you click a big orange button that said “Transmit my returns now?”

When you e-file your federal return you will receive two emails from TurboTax.  The first one will say that your return was submitted.  The second email will tell you if your federal return was accepted or rejected.  If you e-filed a state return, there will be a third email to tell you if the state accepted or rejected your state return.

First, check your e-file status to see if your return was accepted:

If the IRS accepted it, what does it say here?

  Or does your account say “Ready to Mail?”

Note:  If it says “Ready to Mail” or “Printed” that means YOU have to mail it yourself.  TurboTax does not mail your tax return for you.
