When logging from Varac to Logbook, you need to add a few Modes...

You need to add DYNAMIC and VARA HF to the modes.
Do this in Tools > Configure > Modes

If you want to upload to LoTW, make sure you open TQSL and Map Dynamic to Data 

This is the setting for QSO forwarding:

In Logbook go to Tools > Configure >QSO Forwarding and make sure to select your database and port 2333

Also select the Missing fields option and set Merged.
