MacBook Pro 13"/2020 says iMovie cannot be updated because it was refunded or purchased with a different Apple ID.

How can I fix the above problem with iMovie, Numbers, Pages, Garage Band and Keynote in the App Store. I don't use the old iMac desktop with the OS Lion software. It's not working and has not more software updates from Apple. So security is a main issue. Is there a fix? My old Apple ID for that iMac is still linked to a email, actually, the Apple ID is the email that we use for everything. I created a new Apple ID for my iPhone XS Max and use it also on the new MacBook Pro 13". Thanks in advance for any information on how to resolve this issue.
