During Black Friday sale (ended December 7), I managed to talk to the sales rep and bought 7 tax returns (6 for 2017-2022 tax years) and one for 2023 and was charged discounted price. Essentially I got 7 credits to use, 6 of them expire Dec 31 if I dont atleast Print them for each year. So I started each year and clicked on Print to consume credits. The returns can be filed any time and dont have to be by 12/31/2023. As for 2024 credit, I would not use it until the tax filing begins in 2024. Hope this answers your question.
