How i remove my saved payment card in i tunes

Hi!

You can change, add, or remove Apple ID payment methods here: https://apps.apple.com/account/billing. Tap Edit, then tap the Remove icon next to the card you wish to remove.

Please note that if you have any active subscriptions, you must have at least one payment method on file. If you want to cancel your subscriptions, you can do that here: https://apple.co/2Th4vqI.

Hope this helps!
