Hello there, @fittesters.

You'll want to start updating QuickBooks Desktop to its latest release. Here are steps to guide you through:

1. Go to the File menu, then Close Company/Logoff.
2. Go back to the File menu and choose Exit.
3. Right-click the QuickBooks Desktop icon on your desktop, then select Run as administrator.
4. While on the No Company Open screen, pick Update QuickBooks from the Help menu. 
5. In the Options tab, choose Mark All and Save.
6. Mark the Reset Update box in the Update Now tab.
7. Click the Get Updates button.
8. Once the Update Complete appears, close and re-open the program.
9. If you get the message to install the update, select Yes. Restart your computer after the installation. 

You can then proceed by downloading the latest tax table update:

1. Go to Employees.
2. Choose Get Payroll Updates.
3. Click to select Download the entire payroll update.
4. Select Update.
5. Click Close.

Once done, your QuickBooks will automatically do an auto-correction on the next payroll. This is to ensure the employee's payroll information is correct.
