Can I link the work I have done on my taxes on the website with the desktop app that I already paid for?

I started my 2020 taxes on the website. I got to the very end and it told me I had to buy the deluxe version. I had already bought the deluxe version on Amazon. I searched for a way to add my activation key online. The TurboTax help told me I had to download the desktop app. Now I have the desktop app that I paid for, but my taxes are in the website. I can't figure out how to link to the two. There doesn't seem to be a way to log into the desktop app to continue my work.
