I have used that code for over 10 years and it's always worked in turbotax until this year. It's also in the list from the IRS and in the list that turbotax has when you choose find business code. In fact, when you find it in turbo tax and choose it, it puts it in the field and then says it's invalid and shows an error message even though you choose it from the list in turbo tax's own interface.
