Can’t get local channels

I have a smart tv, connected to my home Xfinity internet and I can’t find any local channels. I’m directed straight to a guide with Go To channels. I have an older tv as well that uses an Amazon Firestick and for some reason, I can see local channels on that one. I also cannot get any local channels on my phone via the Xfinity Stream app. Help! This is sooo frustrating!
