Unfortunately, it did not help.  On the Federal Information Worksheet, I checked that the spouse could not be claimed as a dependent on another taxpayer's return.  This had been done before the first attempt at e-filed.  I e-filed the returns again and received the same rejection code.

Thanks for trying.

The taxpayer sis not claiming any dependents on his return.

You have to check the box " can spouse be claimed as a dependent of another person" YES

Even if they can't be claimed as a dependent by someone else?

Yes, it just gets rid of the reject, don't know why, but it works
