How do I stop a tax return that was filled with my info

[DoninGA]

Once a tax return has been filed it cannot be changed, canceled or retrieved

You will have to wait for the IRS to either Accept or Reject your filed federal tax return.
If the return is rejected you can make the necessary changes and e-file again.
If the return is accepted you will have to amend your original tax return. An amended return, Form 1040-X, can only be printed and mailed to the IRS if the original tax return was not e-filed. The IRS will take up to 20 weeks or longer to process an amended tax return.

Before starting to amend the tax return, wait for the tax refund to be received or the taxes due to be paid and processed by the IRS.

No, you can't stop a tax return that was e-filed, even if it is your information.

You can fix the problem. Exactly how you do that, depends on what happened. If this is not a fraudulent return, you need to wait until the return is accepted, or rejected. 

Use the information above to amend your return.

If someone else filed a return using your information without your permission, you need to complete Form 14039 to let the IRS know there's a potential problem. Get started here. 

Complete Form 14039 and follow any other instructions you get form the IRS in a letter. The IRS won't call you, text you, or send you an email as the first contact.
