Glitch in State of MI Turbotax Premier

[uppygal]

Upon entering my local school code, many miles away from the city of Portland,  TurboTax MI generated a City of Portland income tax return for me. I've never lived or worked anywhere near  that city.  I made several unsuccessful attempts to delete the errant worksheets and return. I also tried unsuccessfully to uncheck the Portland box in the city income tax foil.   Finally, I gave up and just annotated the error in the explanatory blurb generated for the errant City of Portland return.  Hopefully,  it does not negatively affect my State of MI or federal return.
