I called Intuit and reviewed the issue. After allowing a representative view the message, then check with their "experts", I was informed that there was no workaround to the error message. I removed all information from boxes 15, 16 and 17, since there is no state income tax, and submitted the return. The frustrating aspect is that this problem has not arisen in previous years - the error message only shows up in a TurboTax worksheet that is created by the program. The tax forms submitted to the IRS are not affected - the income is reported correctly.
