You could not have e-filed a 2018 return in 2020, so not sure what you are seeing online. Did you use the current online software and mess up by entering 2018 income? The online program is ONLY for a 2019 return. The IRS refund site would not be showing a 2018 refund. It only shows 2019 refunds. When and how did you file a 2018 return?
