Get your taxes done using TurboTax

Not sure what to check.  When I run 2018 version and bring up 2018 file everything looks OK.  The LLC partners are all listed.  When I bring up the old 2017 data file with the 2018 program version, like I'm starting a new filing, it imports the LLC members info just fine.  It's only when I try to import the 2018 data file into the 2019 version that the LLC members do not show up!!  What else should I do to check the 2018 file?
