My T4 includes Other Income box 67 in my Box 14. When Turbo shows my Income Summary, it both includes this in Net Employment, and adds it again. How do I fix this?

Box 67 should not be included in box 14, if your T4 shows this it could be an error in reporting on your T4 by your employer.  I have included the link below which explains what the information on each box means on the CRA site so you can review and reach out to your employer if need be for the correction.
