As per the CRA: 

Professional fees (includes legal and accounting fees)

Deduct the fees you incurred for external professional advice or services, including consulting fees.

You can deduct accounting and legal fees you incur to get advice and help with keeping your records. You can also deduct fees you incur for preparing and filing your income tax and GST/HST returns.

It refers to the amount input here

Does it mean the Total income, Gross Income or Net Income?

thanks!

So where do I enter in my gross income re: self employment then?

As per our TurboTax article: Guidelines for Reporting Self-Employment Income

Report your self-employment income on separate lines for each source by entering your gross income and net income in lines 13500 to 14300 of your income tax and benefit return. These amounts are calculated by using the T2125 Statement of Business Activities form which is a part of your personal income tax return. Your gross income is what you have earned before any expenses are deducted. Your net income is what is left over after deducting expenses.

To Enter Self-Employment income (T2125 - Business Statement) in TurboTax Online:

1. In the upper-right corner of your screen, select Find (magnifying glass).

2. In the Find window, type in “self” and select “Self-Employment”. Click the “Go” button.

In my Quickbooks P&L report shows,

Gross Profit equals Total Income minus Cost of goods sold

Is this the amount you are referring as Gross Income above?

Thanks
