I am having the same problem with boxes C and F being checked after I answered that I did receive a 1099-B. I also reached someone at TT and spent 2 hours on the phone with her while she watched me delete the form and recreate the problem multiple times. We never reached a solution and I was also asked to send them an anonymous copy of my tax form. I did so and was told that my file was corrupted and I needed to start over. Obviously this did not solve my problem. There is clearly a bug in this program and it needs to be fixed ASAP. As far as I can tell, they only solution right now is to override and mail my return, including a paper copy of the 1099.
Very frustrating.
