You are seeing that the rental loss is not being allowed for a non-professional. That is quite common. Two requirements to be allowed a passive rental loss is (a) you must "Actively Participate" in the rental, and your modified AGI on your tax return must be under $150,000 (it may be $75,000 if filing as MFS). Otherwise, the loss is carried forward to next year (see Form 8582),
