I have figured it out that TurboTax still has a bug. So, if I delete the imported forms, it cannot be reimported. It sounds like I'm out of luck that TurboTax is going to fix anything. Thus, the suggestion is to wipe out my return that is now finished except for this error, and start a new return using only manual entries for 1099-B. That's a terrible solution for use of an automation tool!
