The 1099-B I received from one of the brokerage firms has incorrect cost basis listed. Do I need to contact the brokerage firm to have that corrected to reissue? Or can I just enter the correct cost basis in TurboTax when filing? If I correct it without the brokerage firm re-issue the 1099-B, will that trigger an alert of discrepancy to IRS?
Thanks in advance.
