Hello there, JDavis409.
Some payroll details don't transfer to QuickBooks Online. But, yes, we can still migrate some information from QuickBooks Desktop to QuickBooks Payroll. I would suggest checking this article to ensure you'll not miss a single detail on how the program converts information from the Desktop product. Then, go to the Payroll and Payroll items section to view the details.
I see the importance of converting all historical payroll data. We can enter prior payroll information manually. Afterward, let's record the prior tax payments as well. To learn more about creating paychecks and timeline processing of Direct Deposit in QBO, you can check this article: FAQ.
Also, you'll see the lists of payroll reports that you can run in QBO bv checking here.
Let me know if you have other questions. Stay safe and be well!
