Thanks for confirming that.
You need to contact EDD immediately and self report the overpayment. It is important that you self report as opposed to being caught. You do not want it to appear that you intentionally violated the law.
There are two kinds of an overpayment:
Non-Fraud: When you have received benefits to which you were not entitled and you are not at fault, because you legitimately forgot to disclose income or were unaware of the requirement to disclose all income earned while you were receiving benefits, the overpayment is considered non-fraud. If this is the case, you will receive a notice telling you if the overpayment must be repaid.
Fraud: When you knowingly give false information or withhold information and receive benefits that you should not have received, this not only can result in criminal prosecution, but with fraud you are assessed a penalty in the amount of 30 percent of the amount of the overpayment and a false statement disqualification of as much as a year. Fraud overpayments and penalties must be repaid.
You are much better off notifying unemployment of the overpayment they made and agreeing to voluntarily paying back the money which was overpaid to you. However, if you say nothing and you are caught, there is also a possibility that you will be criminally charged with fraud---which might entail a jail sentence.
This is one of the few times when coming forward will likely keep you out of jail. Come forward BEFORE they contact you.
Here is a site which, while put out by CA, pretty much explains the way things work in all states:
While it would be preferable if you can immediately repay the money, if you cannot they will work with you on a payment plan.
