Question

I missed checking the box for a T5008 for my husband. I have since corrected it. Now the form is not available to add his info.

Can I over-ride it somehow?

Click on Find (magnifying glass) in the top right-hand corner. Type "T5008" in the box, then select "T5008 - Securities Transactions" from the list, and click “Go”.
Click the “Enter New T5008 for [NAME]” button to add a new T5008 slip.
Enter your information. Remember to select the “Type of Income”.
Click on “Done with T5008” to save your information.
