They want me to pay extra for self employment and I don’t have such thing

If you've entered an amount from any of the boxes on the slips listed here, you have what the CRA considers to be self-employment or business income:

• T4 slip: box 81, 82 or 83
• T4A slip: box 20 or 48
• T4A slip: box 28 and you answered Yes to the question Does the income declared in Box 028 consist of fees collected for services you provided? in TurboTax Online
• T3 slip: box 24 (foreign business income)

If you have an amount in any of these boxes, TurboTax will ask additional questions to report the income as self-employment/business income. You only need to answer basic information, such as business name and address (can be your own), industry code, and fiscal period (Jan 01 to December 31). 

If you are still not able to resolve this issue, please contact our phone support team for more assistance.
