I downloaded Turbotax Home & Business from Amazon. How do I assess Its Deductible?

Go to the ItsDeductible website - https://turbotax.intuit.com/personal-taxes/itsdeductible/

You can access ItsDeductible directly from this link:  ItsDeductible Online. 

Otherwise from within the TurboTax software, you should also be able to access ItsDeductible from the Deductions and Credits screen.

1. Once in your federal return, select the Deductions and Credits tab at the top of the screen.(under the Personal tab in the H&B version)
2. Select the option for "I will choose what you want to work on."
3. Scroll down to the Charitable Contributions section and the ItsDeductible option should be listed.
