Are you talking about the splash screen?
Or in Help - About Realband?

Where does it say 2019?
Another thing to try is to go install the latest update for RB (less download and no account sign in needed).

If you indeed have 2020 (and you should if you have that drive) it will update the product.

Another thing to check is where the shortcut you use actually points to. If you had 2019 previously it is possible the shortcut you are using is not pointing where you think it is.
If you right click it and select Properties you should be able to determine where it actually points to.

I don't recall anyone having this issue this year, so thought I'd mention that last possibility.
