how do i unsubscribe from Apple TV

I signed up for Apple TV, wanted to watch Ted Lasso, and Season 1, Episode 2 came up. I thought it would be a good idea to watch Episode 1 first, but the system kept bringing up Season 2, so went with it. Then as soon as it started I was told there was an error, this happened on 3 trials. So since it was all I wanted to watch, I tried to unsubscribe, but can't find where to do that. I googled "how to unsubscribe from appleTV but the last 2 steps on that don't show on any screens. So how do I unsubscribe?
