Perhaps you should have read this right from the official web site of the court. I have to wonder though why you would look up a number when you knew who it was that called you.
Important Notice about Fraudulent Telephone Calls claiming to be coming from the NYS Courts
It has come to our attention that unscrupulous sources have reached out to members of the public, through phone calls, purporting to be from the New York State Unified Court System, asking for a variety of personal information, including bank account and social security numbers,
Please be on the alert. The NY State Court System never asks, by phone, for financial or family information from members of the public. Do not give this kind of information to anyone claiming to represent the courts. If you are not involved in a court proceeding and have not supplied the NYS courts with a telephone number for receiving court notifications, the courts have no reason to communicate with you by phone and do NOT ask for personal information, such as social security or bank account numbers. To be safe, never provide personal information to anyone who you do not know.
If you have a question about a phone call that you have received indicating that the NYS Unified Court System is contacting you, please call 1-800-Court-NY.

The number itself is of Queens Supreme Court in Jamaica, NY. You probably have left your number in the case file held at the courthouse. This is legit, but again if things don't ring a bell it's wise to ask the caller what it is about - and ask for a number to call back.
