Not taking my american express card

I am trying to pay for turbo tax services with my American Based financial intitution American Express card.  the error is "shippinginfoModel.state(value:) must be between 2 and 2."  I have checked my address on file, it matches.  Everything is correct and active, why will it not take my card?  It is the only card I have and refund deduction is not an option overseas.
