1. Charges to Apple do not show what product or service they are for, on the financial statement. You have to look that up in the purchase history for your Apple Account.

If you have multiple Apple Accounts (not advised), then check for each one.
2. It would not show charges to a different Apple Account which are charged to your payment method. If unauthorized (can be, but doesn’t have to be), then that would be something that you have to discuss with your financial institution (e.g. bank or card company).
3. It has happened to some individuals, that they were charged by someone posing as Apple, using a similar but not identical description. That would likely be fraud. Again, something to take up with your financial institution (e.g. bank or card company).
4. If you are the ‘organizer’ of an Apple Family Sharing group, that also has the Purchase Sharing feature active, then any purchases by the group members get charged to the organizer’s payment method. If you don’t like that, or can’t seem to self-organize restitution within the group, then turn off the Purchase Sharing option. Note that Purchase Sharing is for select buy-items, and isn’t needed for shareable subscriptions.
