On the left, in the online version, almost at the bottom you will find Tax Tools. Click on it and Forms should come up in the drop-down. Click on it and a list of your forms will appear. Find form 3468 and delete it.
Alternately, in the search box (the magnifying glass) search for “delete a form.” Don’t bother doing this until you have cleared the offending entry that generated the form or it will pop back up like a whack-a-mole.
