I'm about to confirm my payment for a tax refund, but its asking for my address and the only option is the United States but I am from the UK. What address do I use?

I worked at a summer camp last year and I'm filling my taxes for then. I have filled out all information and I'm on about to send it off and confirm payment. However, it's asking for an address but the only option is an American address. Do I use my workplace for this? If I don't fill this out, I won't be able to confirm my payment.
