Can some one help me with the Maine Public Employee Retirement add back to the  Federal AGI.  My client's W2 shows an amount in Box 14 with a code of MEPERS.  ProSeries is not adding this amount to the Federal AGI.  Programs says the add back code should be MSRS, ME Public Employee Retirement Plan.   Do I add the MEPERS amount to Fed AGI and pay ME tax on it?  Is it the same thing?  Clarification would be greatly appreciated!
