How you pleaded is not important. How you were adjudicated does. My understanding is you plead no contest to disorderly conduct which resulted in your deferred adjudication. Were the charges dismissed after the 90 days (are the 90 days up?).
All of this needs to be disclosed on your N-400. You can bet it will be discussed in your interview to determine if you are indeed of good moral character. It would behoove you to talk to a lawyer before applying.
