Do I use total prior yr Earned Income from LY joint return instead of current Yr EI (LY > CY) on this years Head of HH return or do I only use my specific income?

Going through a divorce but not finalized.  LY earned income was joint, this years only mine as a head of HH.  LY joint was more than mine alone this year,  Turbo Tax EIC asks for LY EI and uses total reported income.  What is correct, use just mine for both years?
