Resident in CA with rentals operating at a loss in NE and profit in CO, what to claim on state non-resident forms

I am a resident in CA with rentals in NE and CO and am stuck on what to enter in state returns for "portion of rental income" earned in CO. Is this the actual rent received, or rents less expenses? Similar question for NE, where property is operating at a loss. Do I need to declare rent as income? Want to make sure I am not double declaring for for federal and state.
