It's definitely 8960: No Marketplace or ObamaCare (see error message below).
We had no Investment Income, but did have a 1099-NEC. Oddly enough the amount of the 1099-NEC is what's showing in Investment Income on the 8960 form. No idea why. I'll give it a few days and then look again.
"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."
