I think that your products might be hidden. If any of your products in Etsy had their product visibility set to hidden when you exported your data, then those products are imported into Shopify as hidden, as well. If you don't want a product to be hidden, then make it available for the sales channels of your choice.
If not, can you tell me exactly what happened?
