Assuming that you are US citizen/resident ( Green Card ) and that you have been abroad for all of 2018 at least ( thereby you qualify for Physical presence test and make you eligible for foreign Earned Income Exclusion ), where and how are you being paid --- is it all in the USA ( and therefore withholding fully ) or all abroad ( and therefore no W-2) or some here and some there ( i.e. W-2 does not capture your world income ? Are you employed by a local entity? Which country?
Generally when you enter your foreign income ( personal income --> I will choose what I work on --> Other /special situations--> Foreign Earned income and Exclusion ) then TurboTax should open the form 2555 and walk you through this to qualify you for the exclusion. Thereafter the excluded amount should appear as a negative number on schedule 1 line 21 and thus your taxable income goes down.
Is this not what you are seeing ?
