Retirement tax questions

I just found the box I needed to check to be sent to the next screen where I could give the information about my Qualified Charitable Distribution.  The 1099-R I received from my IRA provider indicated only that I had taken a distribution from my IRA.  It also stated that the taxable amount was not determined.  So when I entered this 1099-R in Turbo Tax it showed it as a taxable distribution.  The following screen listed about 9 questions about that distribution.  One of them was, "Was any amount of this distribution given to charity?"  That was the box I had originally missed.  Once I clicked on that box, it took me to the screen where I could enter the information about the charitable distribution.  Then the full amount became exempt from taxation.
