I found a work-around for this bug.
I entered the 1099 R using a wrong amount for box 1 ... e.g.: $1.00
The save the return and close Turbotax.
Then open Turbotax, open the return, edit the $1.00 1099R ... then
change the $1.00 in box 1 to $0.33 - then immediately save the
return and then close Turbotax.
Re-open Turbotax, re-open the return, and the 1099R shows the correct
amount for box 1 .... $0.33
