Hello, I just submitted the income tax for my son yesterday and found some information we keyed in is wrong. Is there a way for me to re-visit , update the re submit it?

Once you’ve filed your return (mistakes and all), you can’t file a new one. But you can correct the original by way of an adjustment.

You must wait until you have received your Notice of Assessment before submitting any adjustment requests.
