After you file

Huh?  We are currently filing 2018 returns for the year that ended 12/31/18.  We don’t do 2019 until next year in 2020.

Are you trying to file a 2018 return?  Then you need the 2018 program.
To do a 2017 return that was due April 2018 you need the 2017 program.

You buy the same year program that you are filing.  What year program did you buy?
