How do I determine the adjusted basis of my business that was sold in 2018

[taxsallout63]

I owned a business for 11 years and sold it in 2018. How do I determine the adjusted basis, when calculating gain or loss?

The Remaining Basis of the Business Assets you have in TurboTax is a good starting point.  

You can add other assets that were included in the Sale of your Business,  but not currently in TurboTax, with their original cost and dates of business use and their remaining basis is calculated for you.

Other non-tangible assets can also be considered, such as Goodwill.
