Where do I enter my UK address to have my refund check mailed to me? The last answer I got said in the 'personal interview'? What is this? Currently stuck on payment page

Also, the last answer I got from you said I can select mail as an option in the Filing section. How do I find this? I only get directed to the payment page and can't do anything here as I live in the UK and don't have a US bank account so I can't seem to proceed at all. Thanks
