Received a class action settlement for withholding payments from a job I held almost 15 years ago in a state that I was not a resident (non-residential college student). Total check amount was just under $600, W-2 is for $78 and they withheld State, Medicare, and UI taxes (all totaling under $5.00). Am I required to file taxes in that state? Do I report the total settlement on my federal taxes?
