Residential energy Improvement credit

In the tax credit section of Turbo Tax, the software calculated I earned a credit (below maximum $2000). However, the tax credit is not applied on the final worksheet which informs me that I am owed a refund on my taxes  (which is mainly due to my large prepayment of taxes quarterly. Three questions:

1. Does my refund status mean I cannot get the tax credit?

2. If I can claim it, how do I add the credit if my software is not allowing it?

2. If I can't claim it this year,can I carry over the credit to next year?
