I just had the same issue for an earlier tax year and called customer support and found out that Turbotax only guarantees the activation code for 60 days and after that you are out of luck unless you can produce the receipt of purchase. Nowhere on the sleeve that you pick up from Costco does it mention the 60 day timeline and customer service says you have to find that fine print on their website. Customer service has advised that unless I can produce the receipt from Costco, I will have to buy a new product from them. Customer service says that they have no record of me buying the product even though I used the code twice already on the same account to file two other family members taxes earlier. Essentially, extremely unhelpful and too bad and give us more money even though you already paid us once--cash grab!
