TurboTax without US address

TurboTax doesn't allow registration without a US address. I don't have one. I can use a friend's, but I'm concerned that this will find its way somehow onto my return.

Last year, following a TurboTax employee's advice, I entered a US address for registration, and it changed my return, AFTER I'd completed and reviewed it. The 2015 return has a foreign street address with a US city and state. Has this problem been fixed, or do I need to use a different tax preparation service?
