State tax filing

Thank you for the answer. I was able to find it! Question I had was for the credit for repayments, do I just enter the amount I had to pay back? Ex if I had to pay my employer back 20k, would I just put 20k then? How would I go about calculating the amount I was taxed? I read that the first $5250 is tax free. But I am not sure how to calculate the taxed amount for 20,000-5250. Would I just use the california tax rate and multiple the amount that was over $5250? Sorry I am new at this.
