The position that TT is taking in their response to this issue is that the sentence -
"If you have to add two or more amounts to figure the amount to enter on a line, include cents when adding the amounts and round off only the total. "
does not apply to the proceeds and cost basis on form 8949. Myself, and obviously many others here, think that interpretation is incorrect but at this point TT has made it clear that it is their interpretation. None of us here are going to change that position.
Personally I think this change was made this year without completely realizing the full implications. That said, at this point TT will NEVER admit that the decision was wrong. In fact they will double down on how it actually is the correct way to do it. Large corporations NEVER voluntarily admit they have done anything wrong in today's environment because they would open themselves up to litigation and their corporate attorneys will not allow that to happen. And trust me, the corporate attorneys are involved in EVERY public statement.
My guess is that they will stick to their guns and not make any changes. Best case they will insist that they are doing it correctly but make an "accommodation" for customers to allow TT to not do the transaction level rounding on form 8949...but I wouldn't bet on even that happening.
