How do I purchase TurboTax PLUS so I can get my .tax file?

In TurboTax Free Edition, you can purchase PLUS to unlock your prior-year .tax file.

The exact instructions will vary depending on the status of your 2018 TurboTax Online return (select one):

• I haven't started a 2018 return yet
• I started a 2018 return but haven't filed it yet
• I've already filed my 2018 return
