I received a form from the local municipality to file my 2010 tax return. I only lived in this municipality?

from 11/6 to 12/31/10, so I am unsure how and where on the form to state the taxable amount. Line 5 of the form asks for the "total taxable earned income" and there is no where on it to fill in the partial amount. Does anyone know how to handle this? Thank you.
