I don't know why your Lacerte program would work any differently than mine but that is not the case with mine. 

Husband received $18k unemployment, wife received $4k.  Each is claiming $11k on their MFS return, each is receiving the $10,200k exclusion which makes complete sense.  If they have to claim the income, they're entitled to the full exclusion.  

UI exclusion is able to be split due to community property rules, citing the ever popular Cahoun case, unemployment belongs equally to each spouse in a community property state
