Close all TurboTax windows on your web browser (including this one). Copy and paste the account recovery website link onto a new web browser window and run the tool.
Use this TurboTax account recovery website to get a list of all the user ID's for an email address. Run the tool against any email addresses you may have used - https://myturbotax.intuit.com/account-recovery
If none of the user ID's received will access your 2016 account, then use the option shown in blue on the account recovery website, "Try something else"
When you sign onto to your online account using the exact same user ID you used to create, complete and file the 2016 tax return you will land on the Welcome Home screen. Click on the blue link - Download/print return.
Or when you land on the Welcome Home screen click on My TurboTax at the top left of the program screen. This will take you to the 2016 Timeline. Under the section Some things you can do: Click on either Download/print return (PDF) or Download all forms and worksheets.
