I already filed my taxes but received another tax form how do I file

You cannot change or add anything on the return that you just e-filed, nor can you stop it.  It is too late, just like when you put an envelope in a US mailbox on the corner.

If you left out a W-2, a 1099G, or a dependent, or a 1099 etc…DO NOT change your return while it is “pending.”  The changes will go nowhere.

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 make the necessary changes to your tax return and re-submit your return. 

 If the IRS accepts your return, however, then you have to wait longer until it has been fully processed and you have received your refund.  THEN you can prepare an amended tax return and e-file or mail  it in. You have to be able to work from that return exactly the way it was when it was e-filed originally.  You will need to use a form called a 1040X.

  Meanwhile, DO NOT go in and start changing anything on your return in the system, or you will make a mess for yourself.  Sit tight and wait until you see what the IRS does with the return you just e-filed

Once your original return is accepted and the finances are settled, you can file an amended return. 

• Save a copy of the original return before doing an amended return. See: 
  • how to file an amended return.
  • I need to amend my state return.
  • Can I e-file my amended state return?
  • Can I e-file my 1040X to amend my return?
• Pay additional tax. Taxpayers who will owe more tax should file Form 1040-X and pay the tax as soon as possible to avoid penalties and interest. They should consider using IRS Direct Pay to pay any tax directly from a checking or savings account for free.
• Use separate forms if amending more than one tax year.
  • Each year on its own form
  • Each year in its own envelope
• Track amended return status online. Taxpayers can track the status of their amended tax return in English and Spanish using Where’s My Amended Return?  Amended returns take up to 16 weeks to process and up to three weeks from the date of mailing to show up in the system.
