I wasted a couple of hours of my life fighting my way to actual (I think) human customer support agents. I asked both of them the same question - how would I know if I needed to refile/file an amended return due to these undocumented changes. One claimed that this would only be necessary if the IRS changed something, i.e., that nothing would be Intuit's fault so they had no obligation to tell me what changed. The other one told me - in so many words - that the IRS would contact me if there were any problems!
