How can I file a late W2 form, when my taxes has already been filed and excepted?

[KatrinaB]

You will need to file an amended tax return in order to add the W-2 income. Please wait until you have received your refund or your return has been completely processed before mailing it. 

When you're ready, follow the directions below to prepare your amended tax return.

You cannot change or add anything on the return that you e-filed.  It is too late, just like when you put an envelope in a US mailbox

Now you have to wait until the IRS either rejects or accepts your return. If your return is rejected, you will be able to go into your account and add or change it and resend it.

If the IRS accepts your return, then you have to wait until it has been fully processed and you have received your refund or paid the tax due. THEN you can prepare an amended tax return 1040X and mail it in. You cannot e-file an amended return.  Meanwhile, DO NOT change anything on your return until you start the amended return. If you did change or add the missing info then take it out and put your return back to the way it was when you first filed it.
