@MaxTax00 If you don't have too many transactions on 8949 that are getting rounded you might be able to use this method instead. I went thru my 8949 and only have 19 entries that are affected. If what TT says is true -
"The rounding differences are well within the IRS built-in tolerances for rounding discrepancies."
Then changing the cents either in the proceeds or the cost basis that TT imports in order to make the calculated gain/loss amount come out correctly so that the totals equal the amounts reported by your broker on 1099-B should also be acceptable.
So here is what I'm going to do. I will go to the imported details for the 19 transactions where the early rounding of the proceeds/cost basis causes the total gain/loss to be wrong and I will change the cents in the imported data on either the proceeds or cost (not sure it matters which one) so that after rounding and calculation the gain/loss comes out correctly (as if the calculation had been done with the non-rounded numbers and then the total was rounded). Then my totals will exactly match what my broker reports on the 1099-B.
