Get your taxes done using TurboTax

I followed the link and this appears to be the process IF I were using the desktop client for 2020 taxes. I'm using the online version instead. Will this allow import into the online 2020 TurboTax Deluxe, or do I need to use the Windows client software instead? If the latter, is downloading the 2020 Deluxe client free given I paid already for online TurboTax Deluxe?
