From another part of forum where Kevin is telling people he took his 55th job of this glorious career well into his 60s/70s.
Oh, and there's another possibility. I worked for Turbotax in 2021. They try to load all the various and sundry ID numbers, rules, tables, etc. into their software as soon as possible---the first few days of January, ideally. With the pandemic, almost none of that info got updated. The IRS shoved the date they would start accepting returns later by several weeks, and even then, there were still massive glitches. It's quite possible that there are still problems.
