I forgot to provide some important details in the form N400. What should I do now?

I already sent my form N400 which is the Naturalization form. I forgot to put one employer's name on that. That employer has nothing negative about me but somehow I just forgot to mention. They have taken my fingerprints already like one week ago. Can I report it at this point? I think I really should, otherwise, it may effect my naturalization process. I'm too scared. Please don't tell me it's too late now.
