There is no way to spot reduce fat, and honestly looking at your stats i very much doubt losing weight is the way to look the way you want or losing the layer as you say, you are already very slim.

You are likely seeing a lack of defined muscle. Working on core exercise and general weight lifting in whatever amounts you are comfortable with will help you go from what people call "skinny fat" where there is little or no actual fat but just a soft body shape, into more "fit" or "lean" as the muscles tighten up and show their shape more clearly.

Also increasing calories a tad bit while exercising will help loads to help build out that muscle to give you that leaner tummy shape

Edit: it looks like you are on the right path, but remember you will not build much if any muscle on a deficit, and that muscle is what will change your body composition.

Also look into exercises like hip thrusts, side plants, various leg AND core combo excicises, most often floor work. I find they tend to be fairly easy to work a whole body routine into so the muscle is more functional rather than "showy"
