I bought the Desktop program from Costco with the $10 credit so we will see how it works when we file state. My package says....Optional in-product add-on purchase must be made via payment card to receive $10 credit at time of in-product purchase.
I think that means when you pay the $20 fee to efile state in the Desktop program. Or if you need to buy a second different state program or buy Audit Defense.
