Please provide some details. What did you type in wrong? Did you e-file?
Depends ... if you did not file the return you can log back in and make the required changes.
BUT ... if you did file already ....
Can I cancel a pending return?
Think of pending as "in transit" or "in limbo"—just like you can't cancel a letter that you sent yesterday, you can't cancel a return that's on its way to the government.
To make corrections or changes to your pending return, wait until your return's either been accepted or rejected.
- If your return gets accepted, you'll need to amend.
- If your return gets rejected, you'll be able to make your changes before you re-submit your return.
