@hanco , in the section on "foreign earned income and exclusion" you report ONLY income earned while your tax home is/was foreign. If you your self-employment income ( even from foreign sources ) but the work was performed with a US tax home ( generally your work place ), then you report the income ONLY on schedule-C. If you had to pay foreign taxes on this "foreign " income then you have to use form 1116 to ameliorate double taxation. In any case this portion is often controlled by tax treaty between US and the foreign country.
Is your tax home in the USA? Did you perform the work at location in a foreign land ( where you stayed for a significant period of time)? Was all of this in 2019? Which country? Are you US citizen/Resident(Green Card)? Were you taxed by the foreign country on this self-employment income ?
