Thank you for suggesting "final review."  Since taxpayer did live with spouse during the year, the rental did
not calculate.  I thought it would be net income, but Proseries figured a net loss when I checked the "not live with spouse during the year" box on the information page.  I'll have to figure why it was a net loss, but the answer is good for now.  Conclusion:  since taxpayer and spouse lived together during the year, the rental will not show on the tax return.
