Thank you for your responses.  I think I will need to file it on paper with the error.  It won't allow me to efile with a 10 digit number.

Yes, they applied and received a Contribution Authorization Certificate from the IL Dept of Revenue and then received a Certificate of Receipt from the School.   The certificate number from the Certificate of Receipt, which is what the instructions for 1299-C say to enter, is 10 digits.

I am trying to include the Certificate of Receipt to claim the Empower Illinois tax credit.  The Certificate of Receipt number is 10 digits, however, I am getting an error from ATX saying its supposed to be 9 digits.  I have called the IL Dept of Revenue and confirmed I have the correct number and it is in fact 10 digits.  Is this a software error, or I am entering incorrectly?  I am entering the credit on page 3 of Form 1299-C.
