If you log in to your Pay Pal account on the Pay Pal site, you can access your "Key". The Key can be linked to a PP credit, your bank acct etc (go to manage my key to select which account). Then click "show key" it gives you a temporary "credit card number" complete with CVV and expiration date that you can enter into turbotax like a credit card. If you have the key linked to your bank account with PP then it will draw from your bank.
