I can't netfile my return because of this error: " Your spouse/partner's income for the year is required to properly calculate your tax return. Where do I enter this?

The netfile error "fix" button doesn't take me to any screens where I can enter her income as zero, which it is. There is no way to file my return (prepared jointly). I can't find any place to enter her income. In fact, in review this was asked for her return to which I answered yes, so what gives??
