A U.S. Citizen is required to report their world wide income on their tax return. They may qualify for a foreign earned income tax exclusion. But it still has to be reported on the 1040 tax return.
Foreign earned income is reported under the Personal Income tab in Less Common Income >> Foreign Earned Income and Exclusion.
Any foreign taxes paid on that income is reported under the Deductions & Credits tab in Estimates & Other Taxes Paid >> Foreign Taxes.
