iTunes vs. AppleTV vs. missing Home Videos

Hello all, I confess I only noted the issue now, although it probably happened much earlier. I have (or would it be: had?) several Home Videos and they were available through iTunes. I don't see those frequently, but wanted to see some and found nothing. Most of these videos are backed up, but few not and unfortunately I am missing most one of these. I have been studying similar problems here in the communities and looking at internet, but so far none of guidances, such as TV app Library and About this Mac> Storage> Manage> Documents allowed me to find these videos. Possibility I deleted them is remote. My iMac runs Catalina 10.15.7

I wonder if someone would be able to help? It would be greatly appreciated Paulo
