One other thing. How did you enter the Form 1099-R in the first place? Did you enter it manually or did you import it from Charles Schwab? If you imported it, I would delete it and enter it manually and see if that makes a difference. If it were me, I'd delete it in any case and re-enter it. You'll also need to re-answer the followup questions after the 1099-R entries.
I found a thread from a user last year who had a similar issue, but found a second Form 1099-R that had been started accidentally, and deleting the incomplete Form 1099-R solved his issue. So when you go to delete your Form 1099-R, you should be able to tell if a second one has been started.
