If it came with a License Code that should be the 2019 CD. The License Code is new for 2019. Did you install the CD? Hen you start a return it will ask for your 2018 return to transfer. That sometimes confuses people.
If you have a License Code it should let you download the program instead of using the CD. Use this link to setup an account to download it
