I used TT Premier to e-file a relative's taxes. She received a notice from the IRS that says the Form 8880 is incomplete or missing. Did TurboTax not send that form?

I'm wondering if the software might have missed that and needs to be fixed going forward.  Aggravated because I rely on TurboTax to ensure all the details are done right, but apparently something went wrong with the Form 8880.  Thanks for any advice or help.
