Get your taxes done using TurboTax

So if I purchase download version,  I assume I just download it once, and then each year, I pay when I do taxes ?

 

Sorry for all the questions....it's just that my daughter has to start doing taxes this year and thought we could do them with my account, but I think I need to buy the download version......   She may need to do taxes for 2023 as well... can she do that if I purchase download (eg, will it let her do previous year's taxes? )
