Greetings, patriciafromdilworth.
I see that you'd like to turn off closed captioning and/or subtitles on your Apple TV. I'm happy to help.
Turn on closed captions and subtitles on your Apple TV -- Depending on which model of Apple TV you own, follow the steps below to get to the "Subtitles" tab to turn it off.
If this isn't the direction that you're going, feel free to get back to me with more information.
Take care!
