Where do i enter a 1099-b for LLC (schedule C)? I have a net loss between Proceeds and Cost basis

I'm using TurboTax Home & Business and trying to fill out the business section.  I have a net loss between Proceeds and Cost basis for investments on form 1099-B.  Breaking out the Proceeds as income and Cost basis as expenses, will produce a large income for form 568 for the State and I would have to pay additional State fee when in reality I have net loss.  How do I fill out the income and expenses correctly in TurboTax so it results in no revenue?
