I believe the real issue may be the instructions need to be updated.

The Reject Value Field is a 4 digit IRS code for why a person did not make it thru the initial, Name, SS and DOB verification. It was located in the top portion of the Acknowledgments rejection report in the Detail section.

ProSeries actually has made it easier now. In prior years, just the Reject Code was there and then you had to cross reference the Code on another list to determine the actual description for the rejection. 

ProSeries now prints the description of the Reject Value in the Detail but not the actual Code number. If you need clarification the instructions directs you to review a Reject Value that is no longer on the report, annoying to say the least.

In the Description: the number in the [ ]/efile: tells you which dependent was rejected, based on their order as reported on the return, followed by an abbreviated description.

The Detail: below the description is the expanded explanation of the rejection. ( the Reject Value).

With multiple dependents you could have [1]/efile:DependentDetail[2]/efile:DependentSSN which translates to the first and second dependent, as listed on the return, were rejected.

If it wasn't all smushed together it would be easier to read, so just focus on the [number] and the Detail. If data you entered is verified as correct by the taxpayer, then the return cannot be e-filed with the rejected individual on it.
