how can i fix this

[ronad]

 

made this table for my record player out of specrite acacia brown timber, I used glue + wood clippings from the saw to fill in the holes from the screws but accidentally sanded a bit too much and exposed the wood, does anyone know how I can restore this so it's the same as the rest of the surface. Do I need varnish or stain or both? Do I need to sand the entire top surface?
