I printed my taxes but have not mailed, can i submit online?

Yes. In order to change from mailing your Tax Returns to E-Filing your Tax Returns (Assuming you HAVE NOT already mailed them), please follow these instructions:

• Login to your TurboTax Account 
• Scroll down to the bottom of your page and click on the blue box "Add a State" (You are not actually adding a state but this gets you to the correct menu)
• Click "File" from the left side of your screen
• Click "Start" next to Step 3 
• Click "I'd Like To Change Filing Methods"
• Choose "E-File" then click "Save"
• Click "Continue"
• From here you can walk through the steps to E-File your return(s)
• Finally, you will come to the screen with the Transmit Returns Now button. This will electronically file your selected returns.

Why I don't see the screen with step#3? do you think that I don't see "step 3" because of the fact that my federal and state taxes had been accepted? i haven't mail any document or payment yet. Any help? 

This is a new forum layout. Some posts that have June 2019 dates are really older posts from the old forum that got moved over. So they might be for prior years and not current info. When they migrated over the dates got changed to June 2019. And the screen shots got deleted. 

If you efiled you don't need to mail anything.  What is your question?

We'd like to efile our taxes, but we had requested to mail them.  How do we change this back to efiling?

You said your returns have been Accepted?  That means you have efiled and are done.
