I enter the same tax information twice when I was filing and I need to delete that tax form because it double everythin and im sure its wrong. How do I delete?

Did you already e-file?   Was the e-file accepted?   If the e-file is rejected you can make corrections to it and then re-file the return.  If the IRS accepted it, you cannot get the return back or delete it.  You have to wait for the IRS to process it fully and then file an amended return.
