I have discovered errors on my reviewed tax form 1040 after filing 4 weeks ago. The program didn't detect the omission of wages, line 7. What happens now?

Turbo Tax reviewed all information prior to submission to IRS.

If you didn't include wages that you received, you'll need to file an amended return to include what was omitted.
