Why is my T5008 listed as capital gains in my summary when it is my sales of investments? My realized capital gains and losses is a few thousand, $90859

In my TD financial report my realized capital gains/ losses is ($255.40) and yet my summary of taxable capital gains reflects the proceeds of disposition/ settlement amount which is $90567.96 (I had cashed out my investments to purchase my house). I did NOT receive that in taxable capital gains. What to do?
