Im not sure

If you e-filed you should not have to print anything to mail, unless you received notice from the IRS concerning a particular form that couldn't be e-filed.   

If you e-filed, check the status of your return. 

Here's help for checking your e-file status:

In TurboTax if you don't see Pending or Accepted as the status, you may not have completed the e-file and you need to Transmit your return.

If you mailed your return:  The IRS asks you wait 4 weeks after you mail your return before looking up your refund at Where's My Refund? 

Most Federal REFUNDS are issued within 21 business days of the return being accepted by the IRS (this is not based on when you filed).  If you are having a check mailed, you will have to add 7-10 business days to the date in Where's my refund to account for mailing time.

 Please keep in mind that once you e-file or mail your return only the IRS has any control over it. 

 The IRS will notify TurboTax when your return is accepted, there are no more updates given for the next 2 stages of Processing and Approval. 

 You have to go to Where's my Refund to get any further information.

Here is help for tracking your Federal Refund:

While most refunds are issued within 21 days of the return being accepted, not the date it was filed, sometimes there can be delays. 

Please see the following information about contacting the IRS if it has been more than 21 days of acceptance:
