Yes, TurboTax has totally botched this. It was not like this last year and now everyone who imports a 1099-B with a large number of transactions is going to get a noticeable variance between what the IRS sees on a TurboTax return and what the Broker sends the IRS. TurboTax is absurdly rounding at the individual transaction level. I am not even sure the IRS allows rounding when further computations are needed... but they certainly don't require rounding this early so don't force it upon us TurboTax. If I was to think of a way for TurboTax to most annoy customers, rounding this early would be near the top of the list. We are not using Pen and Paper so rounding this early is ONLY an annoyance. Any Accountant knows that variances create a huge headache. You can't just assume a variance is from rounding because there might be a more serious issue with the data underneath it.
We have been complaining about it here and are determined to see TurboTax fix it. https://ttlc.intuit.com/community/retirement/discussion/re-rest-assured-this-rounding-difference-wil...
