We've all been there at one point or another. Fill with some scrap balsa if you can then smooth over with some balsa putty.
Use pins or something similar next time to hold the skin in place until you apply the CA. Pin holes are easier to fill then the gap you now have. And a lot less fustrating.

I'm using poly glue and ziplock bags full of lead shot to do my wing sheathing. Nice results so far.
