do I need to refile if I have already filed personal income tax, but did not include the gst from a sole proprietorship that made no money?

my income tax return is on hold, possibly due to this issue. I can't seem to figure out how to file for the business, and I will be closing it after this is sorted out.

Are you registered to collect GST/HST? If so then you'd have to file a separate GST/HST return on the CRA's website: https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/gst-hst-businesses/complete-f...
