I applied for UI in June 2013, I was approved and was sent continued claims and weekly checks for about 6 months. In December I received 4 checks at once and within the next day a notice of eligibility determination. I didn't cash the checks because at that point I didn't know if I was eligible any longer and I didn't want to take the money. They have since determined I am not eligible. I have NOT received an overpayment notice yet, but I am sure that is coming along with a penalty. My question is, is there a way for me to have those check cancelled/returned since they were never cashed and so I don't have to pay a penalty or tax on them?
