Yes, I noticed that too AFTER I bought and downloaded the app and tried to install it. My 2017 iMac was running well on Monterey and I usually try to not fix something that isn’t broken but I caved and updated to Ventura. Update went well, TurboTax installed, and everything seems ok after 1 day’s use.
Side note: I don’t like the Systems Settings change to a long list in the UI, and I REALLY don’t like the pale gray font used everywhere now. I’ve changed the contrast but except for reversing the image (to white text against a black background) there is no way that I’ve found to make text darker in normal modes. Crazy.
