Retirement tax questions

By clicking on the Turbo Tax 1099-R the numbers are not equivalent to the RRB 1099-r (Green Form).  For example: Box 3 on the Green Form is Employee Contributions, Box 4 is Contributory Amount, Box 7 is Total Gross Paid.  Turbo Tax 1099 R - Box 3 is Capital Gain, Box 4 Federal income tax Withheld and Box 7 is - Select code(s) that matches Box 7. 

I have been trying to get this entered for several days and am getting extremely frustrated.
