Hi there AlanTyler,
Thanks for reaching out to Apple Support Communities. It sounds like you have subscribed to a service accidentally but are not seeing the subscription so you can cancel it. We’ll be happy to help.
I sounds like you were looking in the right place for the subscription. If you didn’t see it there, it may not have ever activated. To double check, here are the steps to cancel a subscription: See or cancel your subscriptions.
If you are unsure, you can check with YouTube support to see if there are any active subscriptions through them that we are not seeing. We hope this helps.
Best regards.
