How do I make the transaction screen full screen

Hi there, @anniecampana47.

You can press the F11 key on your keyboard or use the zoom function. so you can enable the full screen in the QuickBooks Self-Employed transaction screen. To do so, please follow these steps:

Google Chrome:

1. On the upper right, select the menu icon (it looks like a three-dotted line).
2. From the menu icon, locate the Zoom option.
3. Select the plus (+) to zoom in and make the page larger and the minus (-) icon to zoom out and make the page smaller.
4. This will work on any page that's either too big or too small, not just QuickBooks Self-Employed. If this doesn't solve the problem, proceed to the next step.

Check these settings on your computer:

Windows 7

1. Right-click any blank spot on the desktop then choose Screen Resolution. Make sure that the screen resolution is set to 1024 x 768 or higher.
2. Select Make text and other items larger or smaller and make sure that the DPI is set to Smaller - 100%.
