I cannot fix "Spousal amount error" in the filing process. Her net income is well below the limit, and no place I can enter her net income manually. How to fix it?

During the filing process, I received "Your spouse's income for this year is required to properly calculate your tax return." When I click fix, the TurboTax brings me to "Are you eligible to claim spousal amount?" and "Is my wife's net income zero?". Her income is less than $11809, so I choose yes and no for these two questions. The error warning does not disappear. Where can I fix this error? Thanks.
