You must be in the Farm Income and Expense section, (I assume you are). Using the Asset Entry section, add a new asset. Describe This Asset, Click "Farm Equipment, Animals, Agriculture", Continue-to Tell Us A Little More About This Asset, click "Farm Buildings", Continue-to Tell Us About This Farm Asset, Description-Cost-(original)Date purchased, Continue-to next page with more details and percentage of use, Continue-use half-year convention, Continue-to question about section 179 (I assumed none), Continue-to Prior Depreciation and enter $5121 (if that's correct), current year (2016) allowed depreciation is $6400. Be sure to click Details and review. If it's correct leave this asset in place. Then delete the 39 year asset. Once the asset is entered, TurboTax will calculate your allowed depreciation automatically each year in the future until fully depreciated.
