I want to stop the reoccurring I tunes charge

If it is for a subscription, see instructions in: How to cancel a subscription from Apple - Apple Support

If it is for iCloud storage that was upgraded from the free 5GB plan, cancel by downgrading to the free 5GB plan. See instructions in: https://support.apple.com/en-us/HT207594

If neither of the above helps, note 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. See each of the steps in the following instructions. They include information on contacting Apple Support if the other steps don't help: https://support.apple.com/en-us/HT201382
