In the newest releases of QuickBooks, the default location of the icon bar is the left side of the window. However, it can be moved to the top, collapsed or hidden.
To move the icon bar, choose the View menu and then select where you want it located.
If these steps do not resolve the issue, you can read discussions and post messages and questions relating to your issue on the Intuit QuickBooks Community site for free or you can contact a technical support agent for additional guidance. Fees may apply.
