Right.  Buying the 2018 Desktop program will not unlock your online return.  You need to call in and tell them you paid for the Desktop program and ask them to unlock your return so you can download the .tax2018 file.


There is no charge to download the 2018 tax data file.  I just did it from my unfinished 2018 online return.
