This can be fixed by changing the DPI (dots per inch) scaling of the Turbotax application by using the Windows 11 operating system, as follows.
Right-click on the Turbotax icon and select open file location, or navigate to the Turbotax executable (.exe) file by any means. Then Right Click on the Turbotax executable file. Select Properties >> Compatibiity >> DPI scaling. Select System (Advanced) Apply , OK, and then exit.
The font should be readable the next time Turbotax is started. It works for me.
