Hi, this is the best I can offer you.
Turbo Tax requires a minimum screen resolution of 1024x768 to display text and images properly. The text in TurboTax is mostly black. Where you would see grey on white is where you would type, for example, the Search Box. See below for a suggestion that may help with your particular system.
You can adjust the brightness and contrast of your monitor to improve the readability of text. Some monitors have brightness and contrast controls on the front (see image below). Or you can follow the instructions below to adjust the setting.
Windows 10 - Open the Settings app from your Start menu or Start screen, select “System,” and select “Display.” Click or tap and drag the “Adjust brightness level” slider to change the brightness level.
Windows 7 or 8 - this option available in the Control Panel >Appearance and Personalization>Display>Calibrate Color
MAC - Choose Apple menu > System Preferences, click Displays, then click Display. Drag the Brightness slider to adjust the brightness of your display.
This is next to useless. TurboTax should have a means to change the text high contrast black on white to support those who are vision impaired such as I am.
