Hi C1vb,
Welcome to the Community. Let me clarify things about integrating QuickBooks Time and QuickBooks Online.
You can only map payroll items to employees, customers, service items, and classes in QuickBooks Time. The option to map payroll items with vendors or 1099 contractors is unavailable. You'll need to enter the pay rates manually in QBO.
Additionally, we've compiled some tips and guides you can use when setting up QuickBooks Time with your QuickBooks Online Payroll. I've attached the link you can visit for guidance: Set up QuickBooks Time in QuickBooks Online or QuickBooks Online Payroll.
Let us know if you still have more questions about the integration or sharing of data by leaving a reply. We'll be sure to help. Take care, and have a great rest of the day.
