Old Billing Address Persists in iTunes. Can't change it. Changed on iPhone (Settings and Wallet)

I have moved and am trying to change my address for all Apple purchases. I changed my billing and shipping addresses on my iPhone (Wallet and in Settings), however, when I look in iTunes my old address still appears. When I select "edit" there is not option to edit, only to add or remove a card. I try adding a card and am not successful. Could this be a problem with it being tied in with Family Sharing and/or Apple Pay? Also, my card's expiration date is approaching and there doesn't seem to be a what to update the new expiration date or the CCV. When I tried to add the new card to ApplePay/Wallet it tells me it already exists.

Thanks!
