Can anyone tell me how to see my return once it's filed?

After the 2019 tax return has been e-filed and Accepted by the IRS, you can download a PDF of your 2019 tax return.

To access your current or prior year tax returns sign onto the TurboTax website with the userID you used to create the account - https://myturbotax.intuit.com/

Scroll down to the bottom of the screen and on the section Your tax returns & documents click on Show.  Click on the Year and Click on Download/print return (PDF)

If the PDF download is incomplete or not yet available, then use this procedure -

Scroll down and click on Add a State.  This will take you back to the 2019 online tax return.

Click on Tax Tools on the left side of the online program screen. Then click on Print Center. Then click on Print, save or preview this year's return.
