Section 179 for rental property

I have rental property which I manage myself, but which is passive income.  That activity earned a profit.

I also have income from a business, on a second K-1, with a non-passive loss.

My husband has a business, on a third K-1, with a non-passive profit.

Our combined K-1's have a positive total income.

I have a section 179 deduction on the above rental property.  TurboTax originally applied it to the K-1 activity for the rental property income.  TT later (for unknown reasons) eliminated this deduction, and is now deferring it to the following year.  Since the activity for which I received it had a profit, my understanding is that I should be able to deduct it.  Am I correct in this?  If so, how can I reinstate the 179 deduction?
