I had the same warning in TT Standard. After the warning and before connecting to netfile this warning popped up. I chose "applies to me" and it took me to the question about selling a property owned for less than a year. The Yes/No choices were both blank, and it was a question I hadn't seen in the interview because I said I hadn't sold any property. It seems like a bug to me. If I haven't sold a property, then I haven't flipped a home either.
