No @mjrengaw, that is incorrect. It has most definitely not always been that way. I'm looking at my Form 8949 from last year right now and TurboTax did not round anything at the transaction level--not the proceeds, nor the cost basis, nor the gain/loss. But for 2020, TT is rounding all of them.... which cumulatively over hundreds of tax lots leads to a $70 discrepancy vs. what my 1099-B shows. Which is preposterous. What's the point of buying expensive tax software if it can't get this right?
