For my 2019 return, I forgot to include one W2. I was working for one day for a company in December 2018 and they put it towards 2019. I didn't receive W2 from them because I chose paperless notifications, so I didn't include it in my 2019 return.
I filed my taxes in May and when I go to check on my refund status is says that my return is received and under review. My guess is that it's because of that W2, even though it was a small amount. I'm thinking whether I should or should not amend because I read conflicting info on the subject.
People say that if I amend it will go to a different department which may further confuse the IRS. So should I amend or should I wait for a notice from the IRS?
