H4 EAD - i 765- C(26)

i have filed EAD application for my wife on 3rd Mar 2020. i sent G1145 form along with I765. Its been more than a week i have not received any notification for the application. I think i made a mistake in filling the Eligibility Category. instead of writing ©(26)( ), i filled it as ©(2)(6). i am not sure if its really a mistake or not. They have not encashed the check as well for the fee so far. Any insight on this would be helpful
