Yes, scratches are hard to repair. The poly, when sanded, turns white and it's almost impossible to feather back in. The good news is it's very durable.
To fix what you've got, wait till it's completely dry and flat sand with a block. Sand until all the surface is flat again. Wipe down with naptha and a rag and start applying with a rag for a flat finish. A lot of work but you won't have to wipe on many coats to get a build.
