What you can do is pay what you can for July. The remainder the court ordered due will accumulate in arrearages, which you'll still owe.
One concept to bear in mind is once a certain amount has been ordered, you are responsible for that. However, going forward, the more quickly you can show your proof of child care expenses, the more quickly you can get the court to reduce your child support obligation.
Also, child support changes over time depending on your income and the other parent's income. As that changes you can file a motion asking the court to re-calculate child support to a lower amount.
Many jurisdictions offer child support calculators, which give a rough estimate of what you'd owe. It's a good idea to use this calculator to make sure when you go back to court you don't end up paying more.
You can find the California Department of Child Support Services' official child support calculator here.
