For what it's worth . . . .
I was able to import a 1099R form in TurboTax deluxe. I also received a printed copy. I got the error referenced on this post. The amount in box 9a in TurboTax was 0.0. When I checked the printed version, it was blank. I blanked out the 0.0 on the 1099R and the error was resolved.
