we ran into the text size & contrast issue last night & while I'm not happy it is the way it is, Im glad there are other who realize this so doesnt work for seniors.
here is the official help page for the Zoom Accessibility function in macOS that @jcapps is referring to (Option-Command-plus) (technically Option-Command-"equal" as you are not pressing "Shift")

it works & makes the TurboTax app window twice as big but we had the same issue of the screen jumping around which was disorienting.
I agree with others and sent feedback to Intuit to add font scaling to their app.
I mean there is only one preference to move a slider to scale forms - why not the whole app?
Here are a bunch of macOS Accessibility options we're going to play with:
