Injured spouse form. I filed it with my taxes online. Do i still need to print it and mail it into the irs?

I saw the answer was to mail it after I e filed...but the e filing said it will be sent with my tax information. I read a question and answer saying mail it seperatly, so not sure if I should leave it alone, or print and mail it to be sure. I don't want my portion of taxes to go to my husbands back owed Child support is why I'm worried!
