Congratulations! You did not screw the top as I can see. I hope the glue will make it!
I made some graphics to explain how I screw my tops onto the bodies. First I drill holes in the middle of two opposite edges:
Then I measure the distance between these holes and transfer it on the plywood for the top (which has a bigger dimension than the body´s aperture):
After drilling and countersink the two holes I screw the top onto the body:
With a router I remove the overlap:
Then I drill two more holes:
I use a small japanese brace ...
... and augers with long centering spikes:
Because I use 4mm screws I take an auger with the same diameter for just the top. The auger´s long spike make marks in the centers of the holes on the body´s edge (after having drilled through the top). Now I can locate the marks with a 3mm auger and drill perfect pilot holes for the screws.
When all holes are drilled ...
... I remove the top and make countersinks for the screws with a box column drill.
Then I screw the top onto the body and round the edges - first with a router, later by hand with stripes of emery cloth.
