My problem was resolved by now. Some detail to share , hopefully to help some folks with same problem.
After I manually typed in the Query ID and token, it worked to import from Interactive Brokers. However, if I copy and paste these numbers from Interactive Brokers to TurboTax, it failed to import complaining about "minimum one character required, etc".
Obviously, the error message is misleading and confusing, since the number on the screen looks fine.
It is a turbotax bug which does not handle/process the "pasted" numbers correctly.
