On this picture of Glacier Bay Elongated Efficiency Toilet, I've added an arrow to indicate where the nut is located.
On top, just behind the toilet seat you've probably already located the plastic flip-up cover that hides the bolt after the seat is installed.
Set a crescent wrench to the size of the nut (underneath where the arrow points) and use a broad-blade screwdriver from the top. Hold the nut stationary while you tighten the bolt from above with the screwdriver.
Frequently, I hear from customers who have cracked porcelain fixtures (like sinks or toilet bowls and tanks) by over tightening bolts.
Your goal should be to tighten until snug and then add only 1/4th turn more.
Should you tighten too much or simply be concerned that you've tightened too much, back off the nut until slightly loose and try again.
