The people on this forum are customers like you and we have no access to your accounts. We can only advise as to things you need to do yourself.
Unless this is a scam you are seeing in an email or a message and there isn’t actually any purchase, purchases are indeed “authorized” by somebody with access to your accounts, or equipment, or with your permission.
Your first step is to try to identify the reason for, and source of, any charges. They may be perfectly valid charges you simply do not recognize. In the case of emails or messages there is the possibility they are not real at all (phishing attempts).
The support article https://support.apple.com/108092 and the related article https://support.apple.com/120164 explain how you can check your iTunes and App Stores purchase history, cancel subscriptions (remember that these need to be canceled at least 24 hours in advance), and track possible sources of unrecognized Apple charges you may see on a bill. These may be purchases by Family Sharing members, others sharing your card (such as a spouse or partner, or a second Apple Account you have; you may not see a receipt).
The article also provides a specific link for contacting Apple if you cannot trace the source of charges, e.g., if you subscribed to something directly with a third party, see: https://support.apple.com/118126 instead. In that case you need to work directly with the vendor, not Apple. See also: https://discussions.apple.com/thread/256198931
If you use Apple Card you may find this document helpful too ➞ https://support.apple.com/HT210618
Also note this service: https://support.apple.com/HT209592
which may let you view Apple receipt details when you are signed into your financial institution website or mobile app .
If using Family Sharing and viewing purchase history under Report A Problem, make sure the “Apple Account” box is set to “All”. If a purchase is listed in your purchase history and you want to ask for a refund, read this article about how to request a refund for apps or content that you bought from Apple ➞ https://support.apple.com/HT204084 Remember that many apps have trial periods with subscriptions that then start automatically unless you cancel them in time. If a Family Sharing member made the purchase then you need to discuss this with that person. They would have to initiate any refund request.
● If neither you, nor Apple, nor a Family Sharing member can account for a charge and it ONLY appears on a bill for a charge card you alone control, you may have been the victim of card fraud. Contact your financial institution immediately. Any reimbursement would have to come from them, not Apple.
