Retirement tax questions

It would have been nice if somewhere it was stated that you must fill in line 16 on 1099-r, even though it was blank or $0, as it is not required by the state or federal governments, just by Turbo Tax.  Never had this problem in the past. Very frustrated, as I have not been able to electronically file due to this, just keeps kicking me back to the 1099-r forms.
