Good afternoon, @Genzeon.
It's great to see you back in the Community. Let's work together to figure out why you don't have the Time Tracking section in the Advanced settings.
To clarify, what subscription/version of QuickBooks Online do you have? If you use Simple Start or Payroll Core, time tracking isn't available for these subscriptions.
Turn on and set up time tracking in QuickBooks Online
Once I know which version you have, I'll be able to determine the best solution for your business. I'll be just around the corner when you're ready!
