Outros attach themselves, by definition, automatically towards the end of the object to which they are applied and typically continue past for some seconds as well. If you just added it you can undo with the usual [Ctrl + Z] key shortcut. If you have saved your project or otherwise made undo unavailable you will have to un-group the outro elements from your clip (the broken chain icon above the timelines) and delete the bits that have been added.
I think the only way to 'move' and outro is to shorten your clip before the outro is applied.
