There is an Apple article that explains how to cancel subscriptions. Click on the following link: If you want to cancel a subscription from Apple - Apple Support

If that doesn't help, be aware that this is primarily a user-to-user support forum; other Apple users like you. We don't have access to information about charges to your account. Apple has a support article about charges — see each of the steps in the following instructions. They include information on contacting Apple Support if the other steps don't help. See: If you see 'apple.com/bill' on your billing statement - Apple Support

If you go in your settings, click on your Apple ID up top and then hit “subscriptions”. That’s going to show you everything you’re subscribed to. So whatever you’re being charged for monthly, if it’s apple it should be on there and you should have the option to cancel the subscriptions, if any.
