You can see the payment methods that the iTunes Store accepts in the Payment Type section. If you want to remove the payment method, select None in the Payment Type section. See what to do if None isn't showing or you can't select it.
Change your information and click Done.
After you change your payment information, the iTunes Store places an authorization hold on your credit card.
Family Sharing
If you’re using Family Sharing, and you're the family organizer, you can’t set your payment information to None. You need to use a credit card or debit card. Only the Family Organizer can edit payment information for a family group. If you're not the organizer, you'll see this message: "The payment method for your Family is managed by [Apple ID]."
