@aliceyy , while agreeing with the post from @DaveF1006 , your comment about two incomes ( W-2 and 1099-NEC/MISC ) needs a little clarification --- I would see this situation occurring when a US person , employed by a US entity works in the USA for part of the year ( and thus being given a W-2 ) and part of the year working from abroad ( thus being given an income statement of erroneously a 1099-NEC/MISC). Note that the W-2 wages cannot be excluded as the work was done in the USA while the 1099-NEC portion of the earnings can indeed be "foreign sourced" because the work was performed abroad. Also the physical presence test 12 month ( test period) will need to overlap a calendar year. Is this your situation ?
Note that for purposes of form 2555 ( Foreign Earned Income exclusion ), you will have to make sure that the net foreign income ( Gross income less any allowable expenses ) is declared as foreign gross earnings for purposes of FEI .
