Have you checked your W2 to be sure that it shows that you worked in NY and not in Connecticut? If you find that your employer reported the wrong state, ask that your company issue you a corrected W2. Call the IRS for assistance if your employer does not issue you a new W-2 or does not send you one in a timely manner, the IRS will be able to assist you. Call the IRS directly at 800-829-1040. If this was an employer mistake then they would also have sent the state taxes to the wrong state, and that also has to be corrected.
Answers are correct to the best of my ability but do not constitute legal or tax advice.
