Legacy Extension warning not found

I have received a warning pop up that there is an extension on my iMac/Catalina 10.15.6 that will not longer work in future OS upgrades.

In the warning pop-up there was no indication as to what or where the offender in located

I read in another thread to go GO/Library and look for the EXTENSION folder.

There is no EXTENSION folder in GO/Library located there

>to that I ask why? Where is the extension folder

How can I determine what Legacy item will not work in the next OS up grade.

Thank you (anybody) who can unravel this new mystery

iMac 21.5″ 4K, macOS 10.15

Launch the System Information app in Utilities and, in the lefthand sidebar, click on "Legacy Software." This will show anything that won't work after installing Big Sur.
