Well, this is weird. I went back to try and recover the original bogus numbers so I could say exactly what was where. I deleted the worksheet and started over with the info from my 1098. And this time ... it seems the numbers came out as I expected. I didn't enter anything differently AFAIK.
So, I appreciate the people who responded and tried to probe to see what went wrong. I wish I could explain. (Note, I'm not a financial sort, but I'm a PhD computer scientist -- I think I can enter numbers into a form, most of the time!!)
