How can I find my 2019 tubo tax data on my computer

To access your prior year online tax returns sign onto the TurboTax website with the User ID 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 you used the desktop CD/Download editions installed on your computer, the only copy of your tax data file and any PDF's will be on the computer where the return was created.  TurboTax does not store online any returns completed using the desktop editions.

Any tax data files and PDF's are stored by default in the Documents directory and in the TurboTax folder on the C:/ drive.

If you used the Windows Desktop program you need the file ending in .taxyyyy to open in it.  The tax files (and PDF files) should be in your Documents then in a Turbo Tax subfolder.  If you can't find them do a search for all files ending in .tax or .tax2020 or .tax2019, etc.  And check the Recycle Bin.  For Windows 10 check the One Drive.  Did you make any backups?  Like DropBox.

If you don't have the main .tax file you might have one that starts with a Tilde sign ~ like  "~your name.tax2020".  That file is if your computer crashes or your real file gets lost or deleted or corrupt so you can restore it.
