I think you are vastly underestimating the extent of this problem.
1. Less than 5% of the actual people that have a problem take the time to report the problem. Most people will deal with this by redoing their taxes from scratch or from a PDF or printed copy.
2. The vast majority of people who file their taxes never look at them again. If people need to provide a tax return, they will get it from printed version or PDF file, not from going back into Turbo Tax. So the 'millions of users' could have a problem that they simply don't know about.
3. Just in the first 3 links of search results for this topic shows over 30 people reporting this same problem with many of them providing details that are remarkably similar. There are 9 other links on this same support topic that I did not even bother going through.
Unfortunately for me, I auto delete my recycle bin on a schedule so I was unable to recover the file from the location most commonly mentioned. Just pissed off beyond belief that this problem has been widely reported for years and NOTHING has been done about it.
