I get the the same error, but the transaction is real, shows on my paper 1099B and gets electronically imported into TT from my broker, which causes the noncovered security box 16 of the 1099B worksheet to get checked, which causes the error. Clearing that box might cause the IRS to see a mismatch between my filing and that of my broker, prompting an audit (perhaps attributable to TT logic bug). ** How do we avoid this?
