I'm having the same problem you're having. Did you ever find a complete response?
Also, it seems that this is not just a TurboTax problem, it's also a Charleston problem. The instructions on the 1099-R don't match the boxes in the 1099-R. For examples, the instructions note that "Boxes 3, 5, 6, 8, 9, 12, 13, 14 and 15 have been deleted from the form." Well, no they haven't, and those last four boxes contain important data.
