K-1 Guarantee Payments

My partnership K-1 shows a roughly $10,000 LOSS in box 2 and an almost identical guaranteed payment for capital in box 4b.  I thought the two would offset when it came to my tax obligation, but TT added about $3,000 to my taxes due when I entered the K-1 data. What's up? (Yes, I have other businesses that showed operating losses, including other real estate I manage myself -- is that the issue?)
