Thanks for the response Lisa.  The only numerical change on the return was the decrease in the standard deduction.  The first time I filed the taxable income went from a big negative to about $300 negative.  There was no change in tax.  The second time, I  removed the refund of the withholding from the original return so there would be refund due.  I got the same message.  I'm thinking you may have hit the answer.  Since there was no change in tax, the system thinks the return does not need to be filed.  Are you thinking there's no way to file this return electronically because ther won't be a change in tax liability?

Thanks for your insight.
