Box 16 of my W-2 has two amounts. Do I need to add them up?

Box 16 of my W-2 has two amounts. The amounts add up to the amount in Box 1.  Do I need to add these up when I enter the amount in Turbo Tax? I only worked for one employer in one state (California). I think that maybe why there are two amounts is that me and girlfriend became domestic partners so I could put her on my insurance.  Thanks.
