i had same issue, same question. But i have no idea how i bought this online (my assumption is i bought it from Intuit, turbotax...) I have a handful of files still on my drive, but none of the program files. While i'm doine with my 2018 filing, now i have this Turbotax files that i cannot open..... I'm not trying to cheat you guys.....and obviously this makes it easier to use turbotax again in 2019
