There are a few options you can try to help you resolve the errors and proceed with your return but it will depend upon how the information was imported as well as the information available to you on your reports.
Based upon what you are describing, it might make sense to enter the overall summary totals as described in this link.
If you decide that might be a better option, you can follow the steps here to delete the originally imported information.
Finally, you can also try to reimport the 1099-B information if that applies to your situation using these steps.
If none of these items address your question, it may be better to contact us using the steps in this link so an agent can review your return with you and provide steps to resolve the issue.
