Deductions & credits

dickzee:
What do you mean by "how to input?"   Input into what?  Please explain exactly what you have done and what you want to do.    Are you asking how to log into the ItsDeductible website and make entries?

Or are you using TurboTax and asking how to enter items at the time of return preparation using the built-in ItsDeductible applet inside the TurboTax program?   Are you asking how to navigate to that built-in applet inside TurboTax?    

If you are trying to get to the built-in ItsDeductible applet inside TurboTax, follow the first steps using the instructions in the answer above, but at the screen that asks "Do you have an account with ItsDeductible Online"  say NO.
If you have entered some charities in that section before, you may encounter a Summary screen.
If so, there is a link "Add Another Charity."
The next screen should say "Let's enter your donations".  Enter the Charity Name and click on the ADD button next to ITEMS.
On a screen that asks "How do you want to value your donations"   choose GUIDE ME.
On next screen enter the Donation Date.
On next screen click button "Add or Edit Items".  
That will launch the ItsDeductible applet that is inside TurboTax.
