I bought deluxe version to file 2018 taxes but it did not take me where I can file and now it keeps trying to make me buy a product which has been paid for.
Sounds to me like you're trying to use the online version of the program. Long story short, that's physically impossible since the online version of TurboTax 2018 has not been available since Oct 16th, 2019.
Did you purchase TurboTax 2018 on a physical CD that you can hold in your hand? Or did you purchase the download version of the CD? If the latter, after you downloaded it, did you double-click the file to physically install it on your computer? If the CD, did you run the setup.exe program on the CD to physically install the program on your computer?
If yes to the above, then there is a "TurboTax Deluxe 2018" icon on your desktop. You *HAVE* to double-click the icon to start the program physically installed on your computer.
