Do I need to amend?

There are too many unanswered questions. Who sent you the email? Did you e-file your tax return? Was it accepted by the IRS or rejected?

I e-filed through TurboTax and my return was accepted by the IRS. The email I received was from TurboTax. It stated box 12 was incomplete. I know for a fact  I had entered information in said box. It appears a few others on this forum are having the same issue. I've never had this problem before and I've been using TurboTax for a while now.

If your return was accepted by the IRS (and you say it was), I would consider this an email sent out by mistake. Please just ignore it.
