I believe you are referring to a Form 1099-Misc reporting other income. If so, you can enter a negative adjustment to cancel it out as follows:
1. From the Federal menu in TurboTax find Wages and Income
2. Find Less Common Income
3. Choose Miscellaneous Income, 1099-A, 1099-C
4. Choose Other Reportable Income
5. Enter a description of the adjustment and the amount as a negative number
