Hi there, @faogsec.

It's possible that one of your employee's information was damage before you convert your file to QuickBooks Online (QBO) that's why it isn't transferred. You can consider entering the information manually in your QBO account.

Here's how:

1. Click Workers from the left menu, then select Employee.
2. Select Add an employee.
3. Fill out the employee's information.
4. Click Done once finished.

I'm adding this article for more details: Add or edit an employee in Online Payroll.

You might also want to check out this article to learn how to process payroll in QBO: Process or run payroll.

Please let me know if you need further clarification about this, or if there's anything else I can do for you. I'll be standing by for your response. Have a great day.
