Since you have already used the correction window option once, you cannot make any further changes and correct the mistake. Although your application will not be rejected due to this.

During counselling, you will be expected to show the proof of Delhi being your domicile and since you won't be able to produce it, you will not be eligible for Delhi's 85% state quota. Also you cannot apply for Tamil Nadu's state quota since you have not filled for it. You will only be eligible for colleges under 15% All India Quota.

Please do not worry about it at this time as you cannot make any changes. Focus on your studies and give your exam well and aim for a high score and rank so that you can get a top college through the All India Quota. All the best.
