I may have fixed it, at least I was able to refile. Still waiting on response from fed, but here's what I did. I'm posting details in another thread.

I deleted my 1099-Rs, continued through steps, then re-added them. Box 4c was now unchecked.
I suspect that the March 13th update did fix the logic for adding an 1099-R but didn't fix an existing one.
