After more looking, the TurboTax 2017 in the Photoshop folder is an older version. One of the TurboTax 2017 apps in Applications is an alias of the file in the Photoshop folder. The other TurboTax in Applications is apparently the latest. Similarly, the Photoshop folder TurboTax is an older version. I also found an older version of Firefox in the Photoshop folder.Yesterday I upgraded my 2012 MacBook Pro Retina from Mojave to Catalina. While poking around, I noticed that the Applications folder has two copies of TurboTax Deluxe 2017. Also, the Adobe Photoshop CS6 folder contains TurboTax Deluxe 2017 and 2018.
