The response Expert Cass0317 gave had a Contact link. That provided a telephone number to call. I was able to talk to a TurboTax representative about the problem. I shared my screen with that person so she could see my problem. While I was on the phone and sharing my screen, I hit transfer efile for Wisconsin and the return was successfully transmitted.
I had previously tried all of TurboTax's suggested fixes and nothing worked. I don't really understand why the return when through for her, but that doesn't matter to me because it was successfully submitted.
