Where do i input agent fees as a self-employed performer?

Self-employment income and expenses (including commissions) are recorded on the form T2125 Statement of Business activities.
 

Commissions paid can be entered on line 8860 for professional fees or 9270 for "other expenses".

If you've already started your return you can use the top navigation to go to Income > Self-Employment. Click "Continue" and TurboTax will walk you through all your self-employment income and expenses.

If you haven't started your return yet, we'll ask you some questions up-front including whether you're self-employed. You can then just continue and TurboTax will guide you through this section as you step through your return.

Thank you for choosing TurboTax.
