Can I claim the work that I had for a few months of 2016?

You certainly can be truthful on the schedules (it's mandatory).

I don't know what you mean by 'claim' the work you did for a few months last year. For purposes of the means test, you must go back through the past 6 months, and state your gross income for each month. Or do you mean, exempt that money (assuming you still have it). Depending on where you live you may be able to claim state or federal exemptions which might cover the sum of money-which you do not mention. You might want to rephrase your question and ask again.
