I want to update my tax return

[xmasbaby0]

Please explain what you mean by "update" your return.  Have you already e-filed?

[TeresaM]

If you have already filed, this information cannot be changed at this time and you should wait until the return is either accepted or rejected.  If your return is rejected, you will be able to modify before you resubmit.   

If your return is accepted, you can amend, or correct, your return if the original entries were incomplete. There is no additional charge to use Turbo Tax to amend your return but you will need to wait until the IRS finished processing the original return. You do not want two copies of your return there at the same time and sometimes they make adjustments. They might even catch the late Form W-2 based on their copy of the form from your employer. Many, many people receive tax forms after they file, so the IRS is used to amendments for this reason. It is very normal for them. 

This is a TurboTax Help article with some Do's and Do nots of amending.
