I'd wait a day to allow any more sinkage to occur and the TO to harden a bit more, then give it a sand down and then apply more TO. For a flat shiny finish, you are going to need lots of coats of Tru-Oil, as each coat is very thin. Many of those you will mainly sand off again if you want a flat glossy finish, as you will be using the first load of coats just as fillers for the grain, so that you end up with a flat surface.

The Tru-Oil coats after that then go to form the protective layer. Even then, you'll need to sand back flat before you can polish it up to a good shine.
Okay, this is encouraging. So the next step is to let it sit for two more days and then sand again? Then I have a few followup questions:

1. The top of this kit is plywood, and it seems to be already rejecting the oil I put on it. Does this mean it is ready for sanding? How do I know the top and sides are?

2. How do I sand the grainy parts? I am asking you to explain this to me like I'm an idiot. I take a 320 grit and sand, and the surface stays just as rough as it was. What am I doing wrong?

That's... yeah that's actually very possible. So to get rid of it I need to get like a milimeter off the wood, right? I guess I'll give up on it.
