Go to their website and fill out the form found under overpayment form on the bottom left side after clicking on employment security services. This is a good place to start. There should hopefully be a number or email that you can reach out to as well.
You can file a claim for Unemployment Insurance (UI) if you worked in New York State within the last 18 months but are unemployed now. You can get up to 26 weeks of benefits while you are unemployed. A typical range of weekly UI benefits, depending on past wages, is about $100-$500 per week.
You have the right to appeal an overpayment determination. You must submit your appeal in writing within 30 days of the mailing date on the Notice of Overpayment (DE 1444). You can still submit an appeal after the 30-day deadline, but you must provide the reasons why you missed the appeal deadline.
If you make $1000 per week in New York, your estimated weekly benefit is $504 for up to 26 weeks.
