Investors & landlords

I've amortized the refinancing fees for a rental property in the past years as depreciation of type L asset (intangible), and I sold the rental property in 2021, can I deduct the remaining refinancing fees? If I enter 0 for the "Asset sale price", there's a validation error on the "Schedule E Wks -> Asset Wks -> Depositions box 21". If I leave it empty, TurboTax is not treating it as loss.
