As long as you entered the Roth IRA contribution in the "Traditional and Roth IRA contribution" section AND you meet all the requirements for the credit, you should get the credit.
It depends on your exact circumstances. If you took distributions from your retirement plans after 2013 but before the due date (including extensions) of your 2016 tax return, this will reduce the eligible contributions that are used to calculate the credit.

Please see page 48 of Pub 590A under the heading, "reducing eligible contributions", for additional information regarding what types of distributions will reduce your eligible contributions.
There are additional requirements concerning your age, AGI, status as a student, and whether you are a dependent taxpayer.

After you answer the questions it will tell you if you got a credit.
To determine if you got a credit, you can review your Form 1040:
