Forgot to submit 8996 - too late?

[T Enterprise]

I filed my corp taxes electronically already. I forgot to attach form 8996 (since Turbotax doesn't have this form). Since I already filed electronically, what would I need to do to rectify this situation? Do I submit my taxes again but paper ones and include this form? Or can I resubmit everything electronically and attach this form somehow?

No, since TurboTax does not support the form you cannot e-file if your return needs it.  Since you already e-filed without it, you should receive a letter from the IRS stating you are missing a form.  You should follow the directions from that to complete and submit your form.
