have to hit tab twice to move to next field in recently upgrade to QB 2021 pro

Hey there, @ap.

Let me share with you some steps that will fix this function issue.

Before we proceed, can you share the type of transaction you're using when calculating the amount? Any additional info would be much appreciated.

I've tried these steps on my QuickBooks Desktop (QBDT) 2021 and use the invoice window to calculate the amounts. On my end, I only have to hit the tab button once in order to move to the next field.

Since you're experiencing this unusual behavior, I'd recommend running the repair tool for QBDT. This tool will help you in fixing errors while the using product.

Here's how to use it, so you can get back to your business.

1. If you haven't already, back up your company file.
2. Restart your computer. This makes sure there are no programs that may affect the repair.
3. Open the Windows Start menu, then select Control Panel. If you're using Windows 8 or 8.1, search Control Panel in the Windows Start menu.
4. Select Programs and Features and click Uninstall a Program. If you don't see Programs and Features, choose Programs instead and click Program and Features.
5. Choose QuickBooks from the list of Programs, then select Uninstall/Change.
6. Click Continue, or Next.
7. Continue by clicking Repair, then Next.
8. Once done, select Finish.

Please take note that you may have to restart your computer to complete this process.

Additionally, ensure to update your QuickBooks to the latest release before performing the steps above. This way, you'll have the most recent fixes and security updates.
