I had the same issue, I'm married and am rounding with a difference of $1 dollar. So, the system is asking for entering the amount as the form received, but when click continues is rounded is another value, so innacure. I don't see any answer in the discussion from TT expert, I hope in the future TT solve this kind of issue. Thanks to the community for this discussion, it helps a lot. I believe the best way to do this is like all suggestions here, do not care about what tt suggestions are said, and do your own round in order to match the right total amount received.
