Qualified Business Income question for Landlord

I am getting asked this question after completing the Rental income & expense section of TurboTax.

 

How should I answer this and how will it impact my taxes?

 

I am a retired landlord with 2 rental properties.  This is in 2018 TurboTax.  B/c I run a loss, I haven't bothered filing past years returns.  I am now getting around to filing all these old returns.
