Allow me to help you fix the payroll error in QuickBooks Online, @Stoychoff.

I recommend going over the information you've entered in QuickBooks again. This ensures that everything is in order. After that, log out and back in to reload the data and double-check that everything is saved.

Before reviewing the information, we can check our system time and date settings to correct them if they are not set correctly. After that, we can go to the Employees or Payroll menu and check the transactions.

If the error persists, we can perform some steps to check if it's a browser issue. I suggest using an incognito window to access your account. This will start with a fresh page and load new data.

If private browsing does not work, I suggest switching browsers. They will give you the best and safest QuickBooks experience.
