If it looks like a phish... Apple will never ask for your Social Security number.
Review recent purchases at https://reportaproblem.apple.com/ or check your purchase history in iTunes and view your subscriptions. If you are the organizer of a family share check for purchases by other members.

If you cannot identify the payment then perhaps you are looking at a phishing email.
If there really have been purchases that you didn't authorize, or you've entered your Apple ID credentials at a fake Apple portal, see If you think your Apple ID has been compromised - Apple Support, change your Apple ID password, and if possible turn on Two-factor authentication for Apple ID - Apple Support.
