Can I get a credit for 1098 T? TurboTax Premier failed but H&R block deluxe worked. This is critical error of TurboTax. Does anybody solve this error of TurboTax?

Hello,
My total income is much less than $170K in 2017, and my daughter is full time collage student.  So, I entered all information with 1098 T in TurboTax to get the credit.  It is first time to try 1098 T credit this year.  But, the final message from TurboTax is 'You are not eligible for an education credit".  I have tried several time, and I could not make credit.  I reviewed IRA regulation and I had confidence that I must be eligible.  So, I bought H&R Block Deluxe version again and entered all information exactly same as information that I have entered to TurboTax.    Then, I confirmed I am eligible to get an education credit $2500.
I tried TurboTax again from starting point (personal information) and I faced with same message "you are not eligible".
Does anybody know how I can solve this TurboTax error?  
I also could not find correct contact of TurboTax about this serious trouble.  Your feedback will be appreciated.
Thank you.
