I am living in the UK. I need to pay my filing fees with a credit card but only have a UK account. How can I pay with my UK credit card?

I have filed for years in the USA using Turbo Tax but this is my second year filing from the UK. I work and live here full time. I paid last year with my refund but this year I don't have any refund and to pay my filing fee with Turbo Tax I need to pay by credit card. I only have a UK account. It wants my US state and zip code but I don't have one. How can I pay using my UK credit card?
