I recently replaced HD and I am attempting to re-install Apps. When I log into App Store and attempted to download an app I get message that my OS needs updating. I am running Catalina 10.15.7.
MacBook Pro 13″, macOS 10.15

Leave safe mode by restarting your Mac normally, then try to reproduce the issue.

As was just posted, the Mac App Store tends to only keep apps compatible with the most recent OS versions, particularly if these are Apple apps. Other vendors may offer older versions too; check the fine print, or sometimes if you go to the vendor's web site and hunt around their support page they may include them there.
If you want or must run an older OS version, you will need to make sure you always have backups of software.
See if you can upgrade your system version, but do make a backup first!
