Because the §1231 loss from the rental is non-QBI, that would not apply to the QBI. However, it is possible that H&R Block is incorrectly doing. Without actually seeing the forms and worksheets it is difficult to know.
But at any rate, if H&R Block is continuing to miscalculate it, you may need to use TurboTax or some other software (personally, I would use TaxAct over TurboTax, but that's just me).
