Thanks for posting in the Community, menotti.
I appreciate you providing detailed information and adding a screenshot. I'm here to get the help you need about adding contractors.
I've checked our records and haven't found any reports from other users having the same issue. To further investigate the problem, I recommend ensuring that you are logged into QuickBooks Online (QBO) with the correct credentials and that you have the necessary permissions to view and manage contractors.
If you still can't find the contractor, it's possible that there was an error during the adding process. In this case, I suggest reaching out to our Customer Care Support Team for assistance. They can help troubleshoot the issue and ensure that the contractor is properly added to your account.
To reach them, click the ? Help button at the top-right corner and select Contact Us to talk with a live agent. Ensure to review their support hours to know when agents are available.
For future reference, here's a great resource to help you close out your current year and prepare for the new year in QuickBooks with your accountant: Year-end guide for QuickBooks Online.
Don't hesitate to let me know if there's anything else I can do to help with your contractors. I'm always here to assist. Have a nice day.
