Is there a way to transfer the desktop return for the CURRENT year to the online version

I started working on the desktop app of TT,  but later decided to move online.

While I know there's a way to import the Last year's return file onto the portal, I was wondering if I can do the same with this year's return saved so far on the desktop.

I tried to import the checkpointed state of the current year's return from my desktop, but it didn't work.
