I am filling Injured Spouse Allocation Form #8379 How do I fill out part II #14?

I have no idea what it means by payments. Is that what you owe the state or something else. Please help. Also on number of exemptions we together put two does that mean I put one for me (the injured spouse) and one for my husband? One more thing. on my taxes there are no cents does that mean when it says 1,877.23 I round down to 1,877.00? my wages are 6,201.50 so is that what I put? I am so confused and don't want to mess this up, please help me.
