On a Mac with a 27" screen I made the turbo tax window very small by dragging the corner and placed it in the center of my screen. I then hit option-command + until the app filled the screen vertically and got something large enough to read the small print. The window will still scroll the entire page up and down. the draw back it every other app running will jump part way off the screen but if you need them just hit option-command minus key and it goes back to normal. So it's back and forth.
another way is I have a MacBook Pro on another desk hooked to a 32 inch monitor so do the same thing there not using any other app and it just a matter of switching chairs to have everything the way you want it all the time.
I find it interesting that this window I'm typing in will allow me to change the size of the text but not in the turbotax app. It is also black text instead of the greyed out text in the app.
Wake up Intuit we don't use 12" monitors any more and grey text has become an industry wide eye strain.
