Greetings Ninabnina,
Thanks for using the Apple Support Communities!
From your question it sounds like you subscribed to a service from an app using an in-app purchase. If this is correct, that subscription or in-app purchase would be tied to that specific Apple ID.
You can make in-app purchases in apps that offer them.
You need to enter your Apple ID password to make in-app purchases. You have two password options to choose from with in-app purchases:
- Always Require: When you make a purchase, you'll always be asked to enter your password, even if you're logged in with your Apple ID.
- Require After 15 Minutes: When you make a purchase, you'll be asked to enter your password only every 15 minutes.
You can also set up Touch ID to make in-app purchases. Learn how to manage your password preferences.
If you have trouble making an in-app purchase, make sure that your payment information is up to date.

If you think you may have made the purchase with a different Apple ID, you can sign into that ID and view your purchase history to confirm.
