I had the same problem with an Oklahoma state return. I could find no way in Turbo Tax (TT) to get around this, since TT kept asking me to identify an Oklahoma property, which did not pertain to this stock sale. Finally, one of the replies to the original question gave me a hint by indicating that this type of problem was handled in the state tax dialogue. TT doesn't seem to have implemented this dialogue. I finally resolved this by opening up the underlying state form and found the state indicated to enter an X in a certain column for transactions that didn't pertain to Oklahoma. This resolved the problem and TT then reported no errors.
