H4-I539 missing information

Hello , I am on h4 and posses h4 ead. My H4 extension application was received yesterday by USCIS . Due to oversight I provided incomplete employer information . I work 2 jobs and pay taxes . I had filled 2 copies for forms but sent in the one which has 1 employer instead of 2 . It is in the additional information section . Please advise . I am very tensed . Please advise. Is there something I can do to rectify. Did anyone had similar issues in past ?

You can refile the H4 extension again to send the extra information.

Thank you for the response. So without touching the current application, can I send another application with additional information?
