What type of property was sold? Residential rental property? Commercial property? Investment property? Second home? Land? Or was this your personal primary residence?
You can use the TurboTax 2018 Premier desktop edition to calculate the gain on the sale based on the type of property sold, just start a New Tax Return. Then in Forms mode you can use the What-If worksheets, select the 2019 tax rates, and the taxes on the gains will be calculated.
