I had a bunch of old ones in there at one point too, sign into My Account with the link here

Then go into Billing, Payment Methods and see if any of them are listed and have 3 dots next to them that you Delete them.  Right now I have only 2 listed, The primary one lets me delete, the other doesnt have the dots (I dont know why)....but I think I got rid of all the old ones in there...maybe you have to make it Primary in order to get rid of it?
