Deductions & credits

Turbotax is disallowing my home office deduction because my expenses are shown on SCH C and as expenses are a negative number.  I am profitable but this profit is shown on form 9747 which turbotax is not recognizing to allow a home office deduction.  Is there anyway I can get turbotax to recognize my bussiness had a profit and allow me the home office deduction?  I am an active MTM trader of securities approver with the IRS already.  Thank you for any help.
