@JMS23 The information provided above is missing an important detail.
The specific paragraph in the IRS instructions that is relevant to the problem that we are describing is this -
“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."
This is what TT is not doing correctly in this specific case and what needs to be fixed. TT is rounding the two numbers, proceeds and cost basis, on form 8949 PRIOR to doing the calculation. What TT should be doing, and per the IRS instructions quoted above, is to include the cents in the two numbers, proceeds and cost basis on form 8949 when doing the calculation and then round the result. That is what TT did in every year prior to this year.
Their are several threads concerning this issue. One of the largest is here-
