As of 3/2/2021 in TurboTax Premier I see the correct amounts to the cents in the lowest level detailed entries imported from my brokerage firm compared with those in the corresponding written Form 8949. However, I have seen several rounding errors (rounding down when it should be rounded up and vice versa) in the next level up in TurboTax. This has caused nearly a $5 discrepancy in the summary values reported in TurboTax versus the summary values reported on the written 1099-B for my account.
Intuit needs to fix this issue in TurboTax immediately. Responses directing one on how to clear out all the entries and enter the information manually are not at all helpful when one has hundreds of transactions to report. I paid about $90 for TurboTax Premier so that the software would handle the data import and calculations correctly, especially since TurboTax advertises its "100% Accurate Calculations Guarantee."
