I rechecked all of my 1099r forms, all of them have a code 7 in box 7, but for one of them I entered (incorrectly) a code 6, as soon as I made the correction the 4a and 4b lines were now in sync AND (unfortunately) my tax due bill jumped by a lot of $. Side comment: the "interview" method for TT is nice, but one should recheck the entries on the actual forms.
