Seems like the TT 2019 software is confused about that (see details above).
And of course the real question that doesn’t seem to get addressed here is: if the IRS allows it, why doesn’t Intuit?
I have used TT for more than a dozen years. The reason I need to file an amended return is a bug in TT. And I just refiled (on paper) ten years of 8606 forms because of a bug in TT 2009. I think next year I will look at alternative software or just learn how to do it by hand. The “tool” I am paying for is really not saving me any time now that I have to fix its mistakes (that I didn’t find originally because I wasn’t familiar enough with the tax code and trusted it).
