The issue: When the 1099-INT was scanned into TurboTax, somewhere the coding(?) read the state as MI (or MT as they read on their screen.)
They deleted and reentered, manually and the problem was resolved.
The error was generated from the Schedule B. Manual entry did not require the address and no error message because there was a state into imprinted into the Schedule B, looking for other address information to match.
