I am receiving the Reject Code F8960-019-04, which relates to Form 8960. My Form 8960 "has a non-zero value" for 'NetRentalIncomeorLossAmt'" How do I resolve this?

I reviewed my actual Form 8960. I cannot figure out why my return is getting rejected. TurboTax does not provide any assistance on how to resolve this reject code. I'm not sure what to do. Has anyone else encountered this?
