Hi @edstoneb
Thanks for posting in the Roku Community!
If it's a Roku TV, there should be a Live TV icon on the Home Screen. If it is missing, you can add it by going to Settings > TV inputs > Live TV > Set up input.
For more detailed information about adding Live TV, visit our Support page here: Set up the Live TV input
Hope you'll find this information useful. Let us know in case you've still got any questions.
Regards,
Karla
