I need to add a code in Box 29 of the T4 slip. Where on an employee's profile to I enter that information in order for it to show on a T4?

Hi AngVL,

Thanks for reaching out to us here.  Having the option to enter employee types is currently not available in QuickBooks Online Canada.  I understand how beneficial this would be and you can submit a suggestion to our Development Team.  In the interim, you can amend the T4 slips on the CRA website.

If you have any other questions, reach back out.  We would be happy to help!
