How do I get a home office deduction on my personal taxes when I have an LLC and income is added via the K-1 Form?

I have an LLC for which I use the TurboTax Business.  I use Turbotax Premier to do my personal taxes.  My question is how do I get a home office deduction on my personal taxes?  When I apply for it, it asks me for income derived from my rental business and that income is added, I am doubling the income to my return, as it is already added when I complete the K-1 section.  When I add no income, it tells me that I am not entitled to this deduction.

What I am doing wrong here?
