Importing your data

The place to check is Schedule 3 Supplemental Statement.  There is a section "From t5008 Slips" in both the before and after June 24th 2024 parts of the form.  Check both sections with and without a date.  You will likely see that they are not being pulled in with no date so your gain/loss won't be included in the roll up to Schedule 3. Assuming you have capital gains, your taxes would go up if they are reported.
