The notice you received should tell you what is considered deficient and therefore what you need to do about it; without seeing the paperwork, it is difficult to be more specific. If you do not have an attorney, there are ways of getting some quick assistance.
Consider looking at the forms at the family law self-help center. https://www.familylawselfhelpcenter.org/self-help
If you are unable to figure it out, consider a consultation at the free ask-a-lawyer event (now done telephonically) every Thursday afternoon, or consult the legal aid center to apply for assistance.
