As long as you have not mailed in your return, you can change to e-file.

 

How do I change from mail to e-file in TurboTax Online?

in to TurboTax Online you'll see the Way to go! You filed your 2020 taxes and you won't see a way to change to e-filing. As long as you haven't already mailed your 2020 paper return, you can switch to the e-filing method (through October 15, 2021). However, some states now require e-filing, which means the federal and state must be e-filed together.

 

If you already mailed your return, don't e-file. This can cause problems with the government, including refund delays.

2. Select Tax Home in the left menu.
