Yes, that is my situation. I have 8606-S because of post-tax contributions but the form computations are fine. No error message on the return at all until the rejection letter comes. I did get an update to the turbotax system today (3-4) so hoping that might take care of the issue.
I also note though that I also have a defined benefit plan that should be reported on line 5a and 5b of the Form 1040 and it is not showing any entry for line 5a. The line 5b total is fine so I did not try to figure out how to override anything into line 5a.
