Get your taxes done using TurboTax

I requested a specific refund amount.  I only got the specific refund amount.  I did not get the specific refund amount plus interest.  I had expected to be paid the refund amount plus interest.  So I need to subtract the interest from the specific refund amount and credit myself in Turbotax for the interest that was included in the refund amount that I had expected to be paid extra for?  How do I do that in Turbotax?  Thanks.
