If the address on your return is NOT the exact same as the BILLING address the card has on file the payment will not be authorized. 

Fixes :

Return to the MY INFO page and enter the same address as the C/D card for now, go to the FILE tab to pay then return to MY INFO to enter the current address before you file.

OR

Update your address on the C/D card ... this may take a couple of days to update in the system so you can  use it.
