Returns with 0 (zero) WFTC refunds are not eligible for electronic filing

This is the error for filing Washington State taxes questions. Washington does not have an income tax, but does offer WFTC. I don't qualify. Why does TT keep coming up with this error, "Returns with 0 (zero) WFTC refunds are not eligible for electronic filing." 

My printed tax forms all have 'DO NOT FILE", "FORM NOT FINAL".

Why???

There are no smart check errors.
