Retirement tax questions

There were four other questions leading to this concerning taxable income.

This was my stumper question;  

Where is your distribution from?

1. Money fm the Teachers Retirement system of GA

2. Money from any fund , program or system which is exempted by Federal Law or Treaty

or

3. None of the above

I had selected None of the above. Because this is Federal Pay and I elected not to have any state taxes taken out.

The answer was #2 money from any fund, program or system.....
