Get your taxes done using TurboTax

My husband worked briefly at a company in 2018 and he never received a paycheck for 2 days of work. We received a late W-2 showing the amount paid as wages in 2018 after filing our taxes. We contacted the company letting them know he never actually got a paycheck, and they issued one in Feb. 2019. Do we file an amended return for 2018 for this W-2, or since he didn't actually get paid until 2019 do we report it on our 2019 tax return?
