That may not be possible in that you will likely double the entries. If you can identify the corrected items, it may be easier to just manually update those items. While we don't know how your corrected 1099-B is organized, if it includes all transactions and then has a separate section for those items that have been corrected (or adjusted), uploading it will also result in double entries. Thus, perhaps the only option is to manually adjust the transactions that have been corrected.
