If your TV supports AirPlay 2, Open Control Center, tap on the Screen Mirroring icon, and Select your TV from the Menu.
click here ➜ Use AirPlay to stream video or mirror the screen of your iPhone or iPad - Apple Support
If using Youtube or another app that actually supports Casting, and your TV supports Casting instead of Airplay, it may appear in Youtube's Casting menu instead.
