I had purchased gold from the bank but had to sell it and incurred a loss. The bank has issued a T5008 for sale price . Should I include the proceeds as taxable income?

Since the purchase price is more than the selling price it should be a capital loss. If so how is it entered in my tax return?

Investors and rental owners

You just need to fill in the T5008 in the program, and TurboTax will calculate any losses/gains. You don't need to enter the amounts any where else.
