Somebody please explain to me?

[I cry_ in_the_dark]

CS support arrears in December at $382.61. Less than one months child suport owed. ($550.00 odered, $253.85 taken bi-weekly)
All payments taken from pay check and current.
As of today, arrears are $551.81. That figure does not even compute to a missed payment.
Documentation from State CS Page show all payments made.
KKKKKKKKK...........somebody tell me?

Even though your payment has been taken from paycheck, the state/child support office may have not posted or credited to the account yet. The additional amounts are interests, I'm betting.  Get copies of the paystubs- or copies/statement from the employer where the money was taken out and directed to the correct office. I'd take it to the child support office and ask for a case history. IMHO, you should not be held liable for interest amounts for the time your payment was sent in and they posted.
