Beveling from tutorial not working for me, can't find a work around So I'm just a beginner and I'm just learning some basic modeling, I'm following this tutorial.

And at 21:00 he adds 2 loop cuts in the middle of the chest and then adds 2 more edges to the bevel but when I do it you get the following. I've already exhausted my limited knowledge and I just don't know what to do. The only way I can think of to fix it is to manually move and rotate the edges so they line up the way they did in the tutorial I cited earlier.
There seem to be some vertices in the middle of the faces of the floor of the chest, inside and out, which are not there in the tutorial. There are edges extending to them from your new edge-loops, and the corners. The floor of the chest should be a plain Ngon. I would go back to before introducing the new edge loops, and check for them.

While you're back there check for other vertices that shouldn't be there.. both ones you can see, and ones you can't. (Right-click to select a vertex, G to move it, right-click again to drop it back where it came from if it hasn't revealed a duplicate, or otherwise acted strangely.)

In edit mode, CtrlV -> Edge Menu > 'Remove Doubles' to get rid of coincident extra vertices.

You may have to delete the floor faces altogether and replace them by Alt - selecting the edges on the perimeters of the new holes, and hitting F to fill.
