Turbo oil return line leak!

[Cupra20]

I've got a leak on my oil return line form the tubo where it bolts to the sump, forgot to put the gasket on when putting it back together and now found it after a first run,

What i would like to know is how much oil am i going to lose when i undo the pipe, my theory is that it should only be what oil is draining from the turbo but i'm unsure,

any help would be appreciated.
