Deductions & credits

also, I don't appear to be getting the screen specifically meant to capture cash donations for a return using standard deduction.  I entered the cash donations in the normal area for entering charitable donations (as if I was itemizing).  I am on the line with TT help right now, they advised to delete all of my charitable donation entries where I put them, and said a screen should pop up elsewhere for me to apply the $600 charitable cash donations for a credit on a return using standard deduction.  But we're not seeing that?
