I'm having the same issue as others in this thread. Made backdoor Roth conversions of $7000 each for my wife and myself. My traditional IRA had $0.86 left in it from a previous year, which I swept up in the conversion. Our AGI is over the limit, so all of the $14000 contribution to the traditional IRAs was non-deductible. Despite following the "3 step" instructions on backdoor conversions carefully and repeatedly, on our 1040, both 4a and 4b show 14000. I expect 4a to be 14000, and 4b to be 0.
I have submitted a file under token number 956738 in hopes that I won't have to wait until 3/31 for a bug fix.
