Two clients - upon e-filing state returns transmit fine. Federal returns message Duplicate Soc Sec Num....  This is NOT a reject as shown in EF Status, it's on the transmit. Confirmed no duplicate SSN in system, no 2nd file, no MFJ-MFS issue. One person posted they had same issue but could not remember how it was fixed. Tried Database Maintenance,  tried HomeBase Tune Up.  Tried holding down Shift key when loading program.

I don't believe it's return identity theft because it's not returning an EF Error Message.  Any ideas?
