<human>: Could you distill the essence of the text into 1-3 sentences?

So in posted here a couple times about my case in small claims but I ran into another wall abs the okc courthouse wasn't too helpful on what I needed. I won $900 in small claims against my ex roommate for breaking the lease and I am supposed to receive a check of $300 at the end of each month for 3 months as per the judgement and the paperwork that was approved by the judge but I still haven't received a check. And there are different kinds of garnishments and I'm not entirely sure which one to chose, one-time, bank, or continuous. I doubt she has all $900 now so I am thinking continuous but this is entirely out of my field and I find can't the answers through google. What should I do?
<bot>: won small claims, didn't get paid like it was agreed upon and I have a judgement and I want to garnish.
