Can I open a download files fax for 2017

Download the PDF of the tax return, not the tax data file (.tax).  Or rename the file extension from .txt back to .pdf since the Edge web browser changed the extension when it was downloaded.  Or change your web browser to either Internet Explorer, Google Chrome or Mozilla Firefox.

To access your current or prior year online 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)
