So I started playing destiny 2 with new light and liked it, so I bought forsaken that came with the pre order bonus, yet I finished the whole campaign and still can’t get it from Amanda

The Forsaken Pre-Order bonus is not included after release. It's no longer a Pre-Order, so you didn't Pre-Order it. Since you didn't Pre-Order it, you will not get Cayde's Exotic Stash, as that was a Pre-Order bonus. The listing specifies that if you Pre-Order, you get it as a bonus. You didn't Pre-Order if you started with New Light; Forsaken was released September of last year, so the Pre-Order time period ended over a year ago.
