Hi,
I believe this is dependent upon your operating system (? Windows 10) and how it is set up. The fonts are selected from the "settings" menu for Windows 10. Similarly the background, is established in the "settings" menu (gear menu). "Normal" font means different things to different people. Therefore, you must indicate "times roman" (little extensions on the letters/numbers) or "Arial" (straight letters/numbers). Also you must indicate in your question if you want dark print on a white background or vice versa. In Turbotax I believe it picks the fonts from the system settings menu. So please state your operating system, the type of characters you want, and whether you want dark letters on a white background or vice versa. We can probably help you more at that point.
