I just amended my return due to a late w2 I just got. However I want to know if I can undo the return and file that W2 next year?

No, all tax documents need to be filed during the calendar year that they are issued. If the return has already been accepted by the IRS, you will need to wait until you receive your refund and then file an amended return.

If the return has been rejected, you can edit the information and then re-submit.

If you need to submit an amended return, you will need to wait until the forms are available sometime in mid-February along with specific instructions. Please see the information below to learn more.

Well I did it on turbo tax and they advised me to print out the amendment and mail it out. It didn't tell me to Waite for February.

The software for amending a 2016 tax return won't be finalized until February. You will also need to wait until the IRS processes the original return.
