I filed but can't print my forms because irs has not accepted - how do i find out what is wrong

How long ago did you e-file?   It may take a couple of days after you e-file for it to be accepted or rejected.

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?  

https://www.irs.gov/refunds         

  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.

If your Efile Status shows 'In Process' then the IRS has not yet Accepted your return.

If it is Rejected, you will receive an Email notification.  Otherwise, be patient and wait for the Accepted status.

Here's how to Check Efile Status. 

You can print out your forms whether your return is return has been Accepted or not, though.
