CSS IDOC for Noncustodial Parent

What should I do if it has past 24hrs and I have not yet received a notification from IDOC for my noncustodial parent. I know that I should have received one because when I look at the status of my application at Tufts, it says that I am missing my 2016 Parent Federal Income Tax Return and 2016 W-2 Form(s). I already finished the IDOC for my mom who is a custodial parent so I know it’s not talking about her.
