I pleaded "nolo" and when I went to turn in the paper, all I did was hand it to a lady and leave.

As long as you're not going to report to a probation officer, I doubt they even test there.

No harm in calling if everything is completed, and ask for the mailing address to mail the papers to.

You could even send it certified and that would just imply you're safeguarding yourself so you can prove they got it.

I do that with everything court related, for proof, not out of any concern for testing.
