You can follow the steps in the support document linked below to find and identify any charges on your Apple account that would show up as "apple.com/bill" on your payment method's statement.
click here ➜ If you don't recognize a charge - Apple Support
and here ➜ If you want to cancel a subscription from Apple - Apple Support
If the charge appears as something other than "apple.com/bill" on your statement, then they are not being charged by Apple, so would not appear on your account. You would then need to cancel them directly with whoever is charging you.
