Hi, if I made the purchase now (Turbo Tax Deluxe). How long does this account eligible? One year?

The 2018 online editions are available to use through October 15, 2019.  After that date if you still need the 2018 program you can request a 2018 installation file download from TurboTax support if you purchased one of the online editions of either Deluxe, Premier or Self-Employed.

The 2018 desktop CD/Download editions are available to use at any time since they are installed on your personal computer.

The TurboTax software is only good for the tax year of the program.  You need to purchase the software for each tax year.
