Sounds like you are in good shape. The court clerk probably never forwarded your license suspension to the DMV. I wouldn't ever mentioned your past history to the DMV again. Almost none of the clerks will care, since it doesn't appear in their computers, and they are petty government bureaucrats. But, you may run into an MADD organizer.
As for the courts, unless you have documentation that you actually turned over your license, they still have a case against you. You may want to look over your court records very carefully. But, unless you turn up again for a criminal driving offense, I doubt that you need to worry about it.
Congratulations.
