Hello Aspirant

Mistakes you did while filling your application form can be rectified during the NEET counseling when correction window opens. You will be notified about it on your registered email id or registered mobile number.

But, there are a few exceptions for details which you can't change once you have submitted the form. Your nationality and category can't be changed once filled and submitted.

Since, you are saying you have not completed the submission process, so if you are unable to find the EWS category option that could just be a glitch. If not then the form is already submitted and you would have to go through the counseling as a general candidate or register again with a new email id and mobile number.

Hope this helps
