Cannot pay filing fee

Hi Turbo Tax,

 

I'm at checkout page and already entered my credit card information, but cannot make the transaction, because it keeps saying the card information is not correct. I'm now living in Vietnam, so I entered my Vietnam billing address, but cannot do it because the "State" field only allows selection of a US state.

Please help me, I want to pay the filing fee to complete my tax filing. But I do not have any working credit card in the US, as I moved to Vietnam since 2020.

Thank you.
