When you go through the Hawaii State return interview, you will come to the credit in the Taxes and Credits section. Look for Credit for low-income household renters:
Taxpayers who occupy and pay rent for real property for a residence within Hawaii may qualify for the credit for low-income household renters. Hawaii AGI must be less than $30,000, and the rent paid during the current year must be more than $1,000. TurboTax will prepare and calculate the credit on Part I, Schedule X.
