Can't Find Home Videos After Migration from iTunes to Music and TV apps

I finally gave up iPhoto and iTunes and went from Mojave to Monterey on all my Macs. My iTunes folder was (and is) on an external HDD, and my setup is so old that my media is in an "iTunes Music" folder instead of an "iTunes Media" folder.

Within my iTunes Music folder were all my songs (thousands) and they migrated to "Music" without a problem by "option-launch-choose a Music Library". Three folders left behind were "Movies", "TV Shows", and "Home Videos".

Movies and TV Shows are all visible in TV app, but "Home Videos" are not. When I have Home Sharing turned on (the new way) Movies and TV Shows are selectable from the "Computers" app/function on Apple TV units, BUT, not so "Home Videos". My Home Videos folder in iTunes contains hours and hours of kids growing up, etc, as well as personal copies of many DVDs which took hours and hours to copy.

Selecting the iTunes Library from TV app does not restore this function. Where in the new file structure does my old "Home Videos" folder go, and will moving it manually restore this important function?
