The TurboTax instructions say "NR" is a valid entry. My previous accountant always entered "NR". TurboTax is also preventing me from signing-off on the error. As I can neither enter information, nor sign off, the return has a prevent filing audit message. I would appreciate any help possible.
I managed to solve the problem. I saved my work, exited TurboTax, then entered the program again. This time it allowed me to enter "NR" in the field.
Thanks to all who offered ideas for the solution!
