Yikes. Sounds like you paid for the Desktop Advantage program last November. But now you are using the ONLINE version. You need to switch to your Desktop program. Did you get it installed? Better sign in to your Advantage account and download it and install it. Then you can move your online return to your program.
First download the .tax file from the Online version,

Then see, How to Switch to Desktop,

After you get the program installed the first thing to do before you open your tax return is to update the program and install any state programs you had. So you first might need to start a fake return to be able to download the state program (go to FILE - New)
Then you just OPEN the .tax2021 file, go up to File-Open. You don't import or transfer it.
