Hello,
Did you populate a valid date range within 2022?
Did you include the HST number of the company you stayed with?
Did you populate all of your personal information into the return before beginning so that it could read you as an individual?
Perhaps it needs a SIN number or something of the sort to function.
I am just tossing out ideas at this point.
I would suggest starting with reviewing the data entry on form ONWS ON479 and going from there.
Regards,
EK
