Wife doesn't have SSN

Hi there,

 

My wife and children don't have SSNs. Based on some research, the recommendation was to add bogus SSNs to bypass the system and file for ITIN or SSN. However, it seems I should have done the filing by mail. Now that I have submitted an e-file, how can make sure to convey this information to IRS? Should I apply for ITIN and mail IRS? 

 

Thanks,

Mohamad
