Turbotax Desktop not providing AOTC credit for my son

I had included my adult son as a dependent in my return and he filed his own return, which was double dipping, so I amended my return to remove him as the dependent.

 

He is in college and had an income of $13000 and capital gains of $500 and 0 income tax. The 1098-T were in his name and was for a total of 42750. He did not have any 1098-Q.

 

When I include all of this data in his return, I expected an AOTC credit of $1000 but Turbotax says this:

 

Not eligible for credit:

 

1. Somebody can claim you a dependent

2. There is no taxable income

3. There were no net qualified education expenses

 

I made sure his return said no one can claim him as a dependent. For AOTC, there need not be any taxable income plus his education expenses were all for a bachelor's degree, enrolled full time with no drug convictions.  I created a brand new return and still have the same results, deleted the student, education section and recreated multiple times with same results.

 

What am I missing? Your suggestions are greatly appreciated.

 

Thanks
