I completely agree. I used QBSE for all of 2018 downloaded all of my transactions and when I started importing data to QBO it was completley useless. 

I've just spent the last 3 hours importing data manually to QBO so I can hopefully get my taxes done today.

QUICKBOOKS, you need to create an easy way to import data from QBSE to QBO, keeping my data in QBSE for a year was pointless after all of this work.
