As an experiment I did as suggested by the office of the president suggested all last year and split trades into small amounts. My gains put on Schedule D by turbotax were off by thousands. Even more annoying is that the UI made it look like the gains being reported were the accurate, unrounded totals.
Simplest fix is to not use turbotax. If it's too late for that and you aren't comfortable with the potential scrutiny you may receive from the discrepancy, you can add a phantom trade with proceeds and cost basis set to the rounding error that you see at the bottom of the worksheet. Name the trade something about fixing turbotax's rounding bug to get the correct gains reported on Schedule D.
