American Opportunity Credit

Got the credit last year.  According to form 8863 we should get it this year.  I have double checked all the TurboTax answers to ensure they are correct.  Yet it says we are not eligible.  Basically our son is going to a university and can not be claimed as a dependent by anyone else.  We are under $180,000 filing jointly and the expenses far exceed what is required.

 

Thanks in advance for any suggestions.
