Received federal return reject code F8960-019-04 - what does this mean? I see nothing I can fix on the return?

Here is the explanation for the reject code that you received: 

If Form 8960, 'NetRentalIncomeOrLossAmt' has a non-zero value, then it must be equal to Schedule 1 (Form 1040), 'RentalRealEstateIncomeLossAmt' unless all of the following conditions are true: 1) Filing status of the return is Married filing jointly or Qualifying widow(er) and 2) Form 8960, checkboxes 'Section6013gInd' and 'Section6013hInd' are not checked and 3) Form 8960, 'FilingThresholdAmt' equals 125000.
