Where is the "Remote button near the top left of the iTunes window"?

The "Remote button" is drawn over with the icon of any connected devices. In your example screenshot, you'd click on the little iPad icon to the right of the dropdown that lets you switch between Music, Movies, etc.

Apple needs to update this help information and improve the wording. >:(

Note that I don't think you have to turn on Home Sharing to use the Connect a Device feature.

It depends on your equipment, but modern routers provide a way to allow devices access to the Internet without giving them access to the any of the shared services that might be running on the computers on your network, which is a useful security feature. If you haven't heard about it then you probably don't have to worry about it. Perhaps firewall settings on your computer are preventing access? That icon shows for me within a second or two of tapping Add an iTunes Library in the Remote app, so if you don't see it that would suggest some sort of connectivity issue. See Resolve issues between iTunes and third-party security software - Apple Support.

Home Sharing did work however. Only Remote says now to turn it on on my computer. There is no other option than to delete the app. Maybe I will consult some help documentation in the future, if there is any.

The button should look like this:

Your device must be able to connect to the same network as your computer uses. It won't work if you're using a guest network or wireless isolation features.

Hello Michael Lunsford and welcome to Apple Support Communities. After doing a little of research about your problem, I have found this website that might be able to help you: https://www.igeeksblog.com/how-to-use-iphone-as-a-remote-for-itunes-to-control-y our-media-library/ I hope this helps!

I have iTunes 12.6.1.25 and I don't see a button that is drawn over with that icon. Also iTunes is taking up 50% to 70% of my processing. 😠

Never heard of. It will not be enough to connect both devices to the nework.
