We have streamlined the process of getting a callback from our Technical Support team, @BarbTarvCo. I'll help you go through it.
Before we proceed, I'd like to ask for additional details on your concern. With that, I'll be able to assist you properly with your concern.
If you want to proceed with contacting our Technical Support team, you'll have to do this from within QuickBooks Online (QBO). This ensures that you're connected to the appropriate support department, depending on your concern.
See this article for the steps: QuickBooks Online Support. Please take note of their operating hours, so you know when they're available.
Feel free to post a comment below if you have other questions about QBO. I'll be around to help you out.
