Loading last year's return

Hi,

I used Turbo tax CD version for 2020 tax year and i have a tax file for it on a pen drive. I had to format my machine so i I lost my turbo tax installation. Now I reloaded the 2020 tax year CD and trying to get my 2020 return information back. I clicked on Open new return and it asks me if I want to save this file or not. If i say No, it looks for my 2019 return which is not what i want. I just want it to load my 2020 tax file.

What should I do?.
