Deductions & credits

Yes, you can force the program back to itemized deduction.

1. Log in or open Turbo Tax
2. Go to federal> deductions and credits>
3. When you see the summary for all tax breaks, press continue through all your screens until you see a screen that informs you that the Standard Deduction is Right for you.  Here you have an option to change to itemized deductions. i will include a screenshot at the bottom of this post to illustrate this. 
4. When you change, continue to the next screen to erase the $300 donation that appears. You are only eligible for this if you take the standard deduction. Be sure to check both boxes in the bottom of the page.
