The sale of your property would be seen as capital gain/loss and hence would be entered as stated below:-
Line 12700: Taxable capital gains
The sale of certain property or shares can result in a capital gain. Line 12700 lists the taxable portion of your capital gains – losses and rate (usually 50%) applied.
Capital gains information can be from T slips such as T3, T4PS, T5, T5008, and T5013 or entered separately.
When you log into TurboTax, click on your tax return, on the left-hand side click on "T-Slip" then scroll down to "T5008", click on T5008 and then enter your capital gain/losses information.
