Thanks for your reply. I have considered that, but the company was set up incorrectly originally and I am looking to close it, move to QB online, and create a new one correctly. I know that I would have to mirror for a while. I was thinking though, that I could save some time later by opening a new one, correctly, in desktop, and entering all my vendors, customers and other basic information, then uploading it all into the online version when I am ready to make the move. It doesn't make sense to spend money to fix a company file that needs to be closed anyway. 

My problems are: reports with information over multiple calendar years; payables (and the payment for them) staying on the payables report; sales tax that cannot be removed (adjusted, JE, credit, nothing takes it off).
