Itunes for PC song total is not visible, version 12.12.2.2

I suppose that Family Sharing might be an answer for you, although I have no experience of it at all. Check out these Apple pages to see whether it might suit you: What is Family Sharing? – Apple Support (UK) and Set up Family Sharing – Apple Support (UK)

If Family Sharing is not to your liking, then how about using a backup programme to keep them in line with each other. SyncToy, with which I have no connection (but I do use) might help. It has options for backup or synchronisation. Apparently, Microsoft no longer offer SyncToy, but it is still available from cnet; https://download.cnet.com/SyncToy/3000-2248_4-10629009.html

On iTunes' menu bar, click on View/Show Status Bar. Alternatively, use the keyboard shortcut CTRL+/ to toggle the Status Bar on and off.
