My foreign earned income exclusion should only apply to a portion of the amount I earned in a calendar year -how/where do I enter that amount in TT?

Physical Presence Test : August 2018-August 2019.  FEIE would apply to income earned January-August 2019, I believe.  I cannot figure out how in Turbo Tax to just note this amount.  (to clarify, all income in 2019 was foreign earned, but because of my physical presence date I do not think I can claim all of the 2019 income under the FEIE).
