Your post appears to not be all inclusive.
What are you doing entering your acquisition costs on your 2019 return, if you purchased the building and started renting it in 2012? If you purchased it in 2012 and converted it to a rental in 2019, then where are you getting a "prior depreciation taken" from?
You've apparently left out of lot of "IMPORTANT" details here. We need more information. Or maybe you're working on a 2012 return? If that's the case, then you flat out can not use TurboTax for completing a tax return for tax year 2015 or older. It *WILL* be wrong, and you can not e-file it.
