K1 income increases my taxes but loss does not decrease it.

Hi,

I have a K1 which shows income, for which I have to pay taxes.

I entered various numbers for box 1 of the K1 into TurboTax to see the impact on the tax. I noticed that losses in the box 1 does not lower my final tax but profit in box 1 does increase the final tax.

What could be the reason for this?

Thank you for your answers.
