Hello @stephen4au
Since I don't have all the details of your tax return, it is hard to say, but I am suspecting that the amount calculated at line 41700 is different because Alternative Minimum Tax from form T691 applies to your situation. Please review the details of that form (T691).
Thank you,
Magalie
You are correct. I figured that out later by redoing everything use the Easy Step. However, I thought double clicking the result of 41700 (green) should give me the calculation form. Instead, double clicking the result of 41700 go to a RESP earning withdrawal form.
