I had the same problem and my SC state return was just ACCEPTED after I made two changes. #1 Make sure your County is set at '88'...this is the code for out of USA. #2, and I think this was the more important change, Turbo Tax tells you that code 008 is because of the missing ISO province. I, at first tried to fix this by going to my SC info worksheet and adding the province there (after getting it from the ISO website). This didn't work...you have to add the province code in the federal 1040 info worksheet and then it flows to SC. I suspect what happens is that the fed worksheet contains the necessary electronic information when you submit to SC. Hope this helps and works for you.
