From what I've read, if Intuit choose to, it could use Xcode 12.1 (released in 20-Oct-2020) which includes SDK 10.15.6 which can produce code targeted for macOS 10.13.6 (= High Sierra). Intuit's choice to use a later version of Xcode which includes a later version of the SDK which can't generate code targeted for macOS 10.13.6 is an (unwise) business decision. A developer finds it easiest to ignore legacy support issues, because they are burden. If I were developing code for myself, I wouldn't bother with legacy support because I wouldn't get any value for taking on that burden. A business that cares about its customers can't afford to be indifferent to legacy support.
True, but then they would not get support from Apple if problems arise since Apple no longer supports it. Also if they want to offer the latest Apple features they must use the current version of developer tools. TurboTax management made the decision several years ago to only use the latest Apple versions.
