You can sign in to access your It'sDeductible here- https://turbotax.intuit.com/personal-taxes/itsdeductible/
If you have already entered information in It'sDeductible, you can import that information from ItsDeductible in TurboTax. You will need to upgrade to a higher version of TurboTax software if you are itemizing your deductions and will be using Schedule A (since donations are reported on Schedule A on your tax return and TurboTax Free Edition doesn't support it).
TurboTax ItsDeductible is a free program that lets you enter your charitable donations year-round so you can import them into TurboTax Deluxe, Premier, Self-Employed, Home & Business, or TurboTax Live at tax time. It's available online and as a mobile app.
