Cancel my taxes

[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.

I don't know why you are asking your question again.  Without any information we don't know if you already efiled or not, and if you efiled, whether it has been accepted or rejected.    So if you have already filed,  please see the longer more-detailed answer that was left for you a couple of days ago by @ DoninGA in this thread.

Otherwise, if that's not your situation, you need to explain more, but don't post any personal info in this public Internet forum.
