How can I get the 2019 turbo tax FILE (not PDF) downloaded on my computer so I can use the retail version?

Transfer from Online to Desktop

1. Save your online return as a tax data file.
2. Sign out of TurboTax Online.
3. Install your 2019 TurboTax software.
   • If you have not purchased TurboTax Desktop software, select the product you need to complete your return.
   • Important: If your return includes a state, make sure you also install the corresponding state program(s), otherwise you'll get Error 539. 
4. Once installed, choose File then Open Tax Return in the software.
5. Browse to where you saved your .tax2019 file, select it, and then select Open.
6. If you get an error, delete your tax data file and repeat these steps from the beginning.
7. Optional: Once you've confirmed that your online return opens properly in the software, you can clear your online return.
