All income and All W-2's are Only entered on ONE tax return.
If you have e-filed your tax return and need to change the information on the tax return then you will need to wait for the tax return to either be accepted or rejected by the IRS.
If the tax return is rejected then you can make your changes and re-file the tax return.
If the tax return is accepted then you will have to amend the tax return to make your changes. An amended tax, Form 1040X, return can only be printed, signed, dated and mailed by you to the IRS, it cannot be e-filed. The IRS will take up to 4 months to process the amended tax return. Wait until you have received the tax refund or the taxes owed have been paid and processed by the IRS before amending the tax return.
Once your original tax return has been processed you will need to file an amendment to add the missing W2 information. You may get a letter from the IRS noting this missing income and giving you instructions. To prepare an amendment in TurboTax, sign back in to your TurboTax account. You will see an option to amend. Choose that option and follow the prompts to complete the task.
