Thanks for your reply and link to list of authorized dealers. While I waited for replies to my question, I decided to call TurboTax. After a long wait, I spoke to a woman who reassured me that "Big Home Tax" in the UK is, in fact, an authorized TurboTax dealer. So it appears that TurboTax needs to update it's list to include them. It appears that the list you link to is just US dealers.
