The 1099-misc always ends up on Schedule C, although it can get there either by being entered as personal income or as business income. In either case it would ask about business expenses also. You don't, however, enter it twice. If you've already entered it as business income then don't enter it again. You should see what you entered in the business section.
To check that your 1099-MISC has been handled correctly by TurboTax, go to View > Forms and look at your Schedule C. Line 1b should show your correct 1099-MISC amount.
