Hi there, Michelle. I appreciate your prompt reply.

I can share the process of exporting payroll data into QuickBooks Online (QBO).

Right now, importing payroll data in QBO is unavailable. While our engineering team are still working on the error you get when exporting your payroll data from QBO Payroll Core to QBO Plus, you can enter your payroll data in QBO instead by making a journal entry or recording them through the prior payroll process. 

For more details on entering your employee’s year-to-date paycheck info and company totals, see this article: Add pay history to QuickBooks Online Payroll.

If you don't want to enter your payroll data manually, you can wait for the investigation to be resolved so you can export your payroll data through the Preferences in your payroll account. For more guidance, see this article: Export your payroll data into QuickBooks.

For future reference, here's an article in case you'd want to run reports to view a snapshot of your business: Run reports in QuickBooks Online.

If you have any further concerns, feel free to reach out. Have a great day!
