Just because you don't receive new claim forms does not mean that the EDD has denied or canceled your claim, as there are many other explanations for this, and the EDD will not automatically cancel your claim just because you report earnings to them.
If it's the first time that you reported earnings, EDD may temporarily stop your payments in order to schedule an interview with you to discuss your employment. This would result in them holding up your claim forms.
However, as long as you are making less than your weekly benefit amont, you are entitled to unemployment benefits, and they will be reinstated once you have your interview with EDD.
You should contact EDD directly to request new claim forms at the website here:https://askedd.edd.ca.gov/asp/frmEDDCOMM.aspx
1) Select the category 'unemployment insurance benefits.;
2) Select the sub-category 'claim form' &
3) Neeed replacement claim form
and then fill out the information requested to get your new claim forms.
The EDD will respond to you within one or two days to inform you of the situation and should send you out replacement claim forms within a week.
