After you file

No, I would not amend if I were you. Just to let you know, the IRS is not yet accepting returns for processing as they are starting this on the 12th. So, technically, your return is sitting in a queue waiting for them to "take it in", so to speak. In addition, your W2 information is what they've also received so there will be no discrepancy at all that would be visible to them. They receive a W3 Form from your employer which details every W2 that the employer prepared and sent out to their employees prior to your receipt of your W2. You're all set!
