@rwom1217 , agreeing with my colleagues @Mike9241 and @DoninGA , I would urge you to recognize the "private" sales proceeds i.e. amend the return. I say this because when you file a return ( electronically or by mail ) you are submitting this as a true account of your incomes ( & allowable deductions ), under penalty of perjury. IRS may or may not catch the un-recognized income, but if they do , you will on their watch list for the next three years. Therefore and because of perjury jurat, I will take the trouble of setting records straight. That is my suggestion -- of course what you do is up to you.
