First time setting up an amazon item for sale. They want all sorts of info, I have to give the reason for my exemption. But it only lists "product bundle" or "replacement part" as options. Neither is the case with my 3d printed item. At the bottom it wants a product id. I tried using the SKU that I was told was approved in the exemption but its not taking it?
