According to live agent I spoke with, she said you can only use all 8 returns in one tax year! Meaning you should have filed 8 returns like for each people submitting their return that year you purchased the said deluxe box. So good for 8 returns (8 people) so sadly if you purchased it like me for you and your spouse thinking you can use it for both of you for multiple tax years thinking you both can submit up to 4 years, turbotax don't want that much savings for us they are greedy and want your money each year so must purchase said deluxe box per tax year. I suggest you try Rakuten then get discounted turbotax submission $16 approx per person
