From your answer and the fact you say you do test returns, I'm guessing your QA or someone who does a lot of these. Please remember the I and most of the people doing this, only do this once a year, and the interface changes every year. Now I just had this issue and when I started, I remember that it asked me if I had a Identity Protection Personal Id pin and I answered yes. I had the sheet ready. I never got a prompt.
"So while I was typing this, my return was rejected, and I was able to enter the pin and refile it. A few notes, I went to that section, it was not highlighted, I had to hit the drop down. It did not say revisit, like everything else I had to enter last year. So this is not intuitive and is easy to skip. Fortunately for anyone reading this, it rejects fast and is easy to fix. "
TurboTax should fix this. I had one issue and now I get a CP01A every year, so if one was entered the year before, they should be able to tell that one is needed this year.
