I submitted a 1099-MISC to the IRS for a contract worker through another accounting service. Where do I enter the amount that I paid him on turbotax?

It goes under contract labor.  

There are 17 unique categories for entering business expenses in the TurboTax Home and Business program for a Schedule C.  If you have a particular expense that does not fit in the other 16 categories listed use Other Miscellaneous Expenses at the bottom of the list.
