This is EXACTLY the bug that happened in the 2019 version of TurboTax, which they finally tracked to some programmer test code that accidentally got left in the product that shipped. Very shoddy software engineering going on at Intuit, if they create a huge bug, finally acknowledge it and track down that it's their fault, and then the following tax year, make exactly the same mistake.
Intuit software is the only MacOS software I've ever found that creates corrupted files that have to be deleted to restore normal operation. Perhaps they spend thousands of hours testing it on Windows, with which they're more familiar, and then do a superficial job of testing it on MacOS?
