Hey there @vibesofeuphoria! The billing page has a "Billing History" tab that has a box at the top about your current (if any) saved card information. If one is stored for you, it will tell you what kind of card it is (Visa, MasterCard, etc) and also the last 4 digits of the card. If that's not the right card, you can also delete that saved card from the same place (click "Delete existing payment method" below) and/or add a new one with the "Add new payment method" link. Since we don't store the full card information, there's no way to "edit" the card on file; however, you can always remove the saved card and add a new one if there is any confusion.
Does that answer your question? Happy to help further and/or answer any other questions! Welcome back! :)
