Get a very small drill and run it down the side of the screw in perhaps
6 places. This removes enough wood to free the screw. Then drill a large
hole suitable for a wood dowel. Glue it in and then, when glue is dry,
trim to be flush with a chisel. It's possible to fit a second dowel next
to the first if you allow the glue in the first to dry before drilling a
second hole.

That works OK but the grain in the dowels runs in the wrong direction so
may not retain screws very well. If screw retention or appearance are
important (hinge screws, for example) I make plugs using a plug cutter
and then the grain can be in the appropriate direction.
