Retirement tax questions

How does Turbotax not understand that because they are rounding sooner than necessary, they are making life very difficult for their customers in trying to reconcile statements?!?  If you have enough transactions and Turbotax rounds all of them at the individual transaction level then you get uncomfortably large variances between the total that a TurboxTax produced return provides the IRS and what your Broker sends to the IRS on something like a 1099-B.  Fix it, please. I do not recall  having this same issue in any of my prior decade using Turbotax.
