It sounds like you are the recipient of a 1099. If I am wrong, please correct me in a comment.
If I am right, you will file your business income and expenses on IRS Schedule C. TurboTax will complete the Schedule C for you once you enter your business income and expense into the program.
To find your way to the right section of TurboTax, type in business income in the search bar and then click the Go to Schedule C box.
