You don't use TT to answer an IRS inquiry ... send them exactly what they asked for... proof of income and/or an explanation of how determined how much you were paid ... you must have some proof that you received this income in some format. Mail your response back to the address on the notice as directed.
AND is sounds like you mailed in the state return with the federal return ... you must mail in the state to the correct state mailing address so if you want it filed you must do so.
