No one can do anything to your tax return. No one in the user forum can even see your return, much less make any changes to it. If you entered some wrong information, delete the wrong W-2's or clear and start over.
CLEAR AND START OVER
If you only want to remove the W-2s and not clear everything:
On the menu in the sidebar on the left.
Select Tax Tools
Xmasbaby0 has given the link to Clear and Start Over.
