CSA 1099R block 7 (3-Disability) and Block 2a Unknown

My wife became disabled while working for OPM.  We received a CSA 1099R with Block 2a and UNKNOWN and Block 7 (3-Disability) which has been the same as last year and all prior year.  Turbo is trying to put her wages in Line-1 of the 1040, which in turn messes with the state docs.  Any information of the proper way to correct this would be greatly appreciated.
