How do I cancel Apple care for a device I no longer have?

I can’t figure out where to access my Apple Care to cancel an account for a device I no longer have? I just got billed for this month so I want it cancelled for next month. It said on the email they sent to do it in my Apple ID. I checked in my settings subscriptions and can’t find Apple care. I actually can’t find it anywhere. I suppose it could google it but this is where I was directed. Any help will be appreciated!
