How do I plug the countersunk screws when starting and finishing the deck

You will need to use a countersink tool first for the screw. Once the screw has been fitted use a plug cutter to get a plug from a sample of the decking you are installing. Insert the plug with some PVA glue, then trim with a chisel and sand to match the surrounding timber.
