Tax Year Prior to 2020: Where do I sign up for direct deposit

@Correengraham78  Could you clarify your question?   Are you mailing your return or Efiling?  We can't see your tax return in this forum.

If you are Efiling, there are no documents to sign, and TurboTax will notify you when your Efile is Accepted. 

Click this link for details on How to Efile.  You can also Sign In to your account to check your Efile Status. 

If you are Mailing your return, you will need to sign your printed Form 1040.

This link has info on How to Print and Mail Your Return

As you step through the FILE section, you are asked where you want your refund deposited.  If you used TurboTax last year with the same Sign In, you can default to the same deposit info, which will be filled in for you. 

The IRS will begin accepting Efiles on January 24.
