How do I take sec 179 deduction on a K-1 with Section 179 deduction amount of $6244? Getting an error msg "..change amount you choose to allocate..."

Entered K-1 with $15000 income & sec 179 deduction of -$6244.

Getting message: "...limited to zero.You must adjust sec 179 deduction by $6244 on one or more activities.  Change the amount you choose to allocate to schedule K-1...only if adjusting the deduction amount."  

How do I get TurboTax to allow the deduction?
