Hi, I'm having the same issue that the sum of all of the Box 21's of all my T5008 forms are being summed and reported as 'Other income' on the income summary tab of my TurboTax return. I HAVE filled out all of the box 20's indicating the book cost (which in many cases is higher than the proceeds box 21).
How can I prevent all of the proceeds from Box 21 from showing up as taxable income? Thanks.
