I backed out all information about recharacterization and double checked that no roth contributions were indicated. I'm still getting the excess contribution notification.
I suspect that there is a bug in turbotax software. The 1099-R functionality was delayed and clearly they don't have it quite right. The help articles also no longer match the questions you get asked. I'd hate to move off of turbotax as I've used it for many years, but this might be the last straw.
