if that $47,000 was w-2 income then you made have erred in entering the federal withholding.
or maybe you didn't enter any estimated tax payments made
based on the tax tables with about $22,400 in taxable income they call for a joint return tax of about $2,300 + about $70 or so in SE tax.
a $00 tax would imply taxable income of only $3,000
