Didn't show up to court for speeding violation and totally forgot to submit a plea. Did I do an oopsie?

So basically I got a speeding ticket that I wasnt going to fight so I decided to not go to court. Today is day 3 past the 2 weeks that I was supposed to submit my plea, however, I absolutely forgot to. I just paid my fine online with no additional charges, and my license is still valid. The court opens on Monday. What should I do? What should I expect?

Thanks!
