redeemed itunes gift card but still wants my credit infor

Hi biscuit11,

I understand you are experiencing issues redeeming credit from a gift card. Have you attempted to update your payment information, and then trying the purchase again?

Change or remove your payment information from your iTunes Store account (Apple ID) - Apple Support

After updating your payment information, you can check to see if your gift card balance is accurate by following these steps:

See your iTunes credit balance - Apple Support

Thank you for contributing to Apple Support Communities.

Take care,

and then after this will this give the option of redeeming the gift card or will it purchase it thru the credit card
