Where do I enter my Foreign Earned Income Exclusion? TurboTax determined I am eligible but it's not computing the amount--my tax due is 3x my income. Where do I enter it?

I live overseas and am self employed. Through 2555/FEIE I am eligible for my 100% of income to be excluded. Total SE income = 19175. FEIE = 18940. But my Federal Tax due is the same amount regardless. Do I enter the 18940 elsewhere to have it deducted?
