Photos from macbook to apple tv

I have a Macbook, running Catalina 10.15.1. All photos on iCloud and all

work well between devices. For many years I have been running our

photos through Apple TV via Home Sharing on iTunes. Now of course with

Apple Music and Photos this option has gone. I have checked and been

told that I need to turn Home Sharing on via

Apple>Preferences>Sharing but when I go there I do not see Home

Sharing on the screen. I can get my Photo Stream, ie the last 350 or so

photos on Apple TV but when I try to bring up anything else I am told

that there is nothing in the Activity section, ie I cannot bring up our

Albums. The Screen Shot below is what I see when I go to the Sharing screen, no Home Sharing.

I am at a loss. Any ideas anyone? TIA
