I have imported expenses from QB desktop, and they show up at "checks" in my register. Is there a way to change them to another type so I can move them to a new register?

Hi there, rrcoffee-cr-gmai. 

I'm here to ensure that you'll be able to change the transaction type in QuickBooks Online. You'll need to delete the checks to change the type of transactions to expense. 

Here's how:

1. On the left panel, click Employees.
2. Click An Employee, and go to the Paycheck list tab.
3. Choose, and click a Paycheck.
4. At the bottom menu, click Delete or Void.
5. Put a Check Mark in the I understand that this action cannot be undone box.
6. Click Delete Paycheck.

I've added a related article to guide you on how to manage expenses in QuickBooks Online.
