@gaili-zhao Hey if i may ask respectfully how did you end up E-filing your E*Trade erroneous A-coded cost basis on 1099-B?
Did you file with the discrepancy in place (between the erroneously A-coded 1099-B cost basis and the correct one from final K1) expecting a letter of explanation and if yes did such letter ever materialize?
If you didn't take the risk of the discrepancy how did you resolve it? If E*Trade reported A-coded defective basis then did you just take the hit and pay unnecessary (presumably higher) income tax at the end?
Thank you
