Notice of Determination (EDD) ?

Hello everyone, 

I started receiving unemployment around 4/05/2020 due to covid 19. The last payment I receive was around 09/05/2020. I stop certifying because I was getting paid normally. Recently I received a "notice of determination" stating I am not eligible to receive benefits because I did not provide identity verification and have a chance to appeal. 

I heard about ID.me but I never did identify verification because I was no longer Certifying. 

The only thing I am worried about is from 4/05/2020 - 9/05/2020 - The status of my certify history went from Paid to Disqualification. I already got all the money since these was a while back. 

I was wondering if I do not appeal, do I have to give all the money back?  

Thank you!
