So long as the home becomes your main home or second home on the day it's ready for occupancy, you can deduct all the interest you paid on the construction loan within 24 months before the home was completed.
TurboTax asks if you bought or improved your main home in 2023, which is not the case. The loan must be secured by the property in order for the interest to be deductible.
