Deductions & credits

 @  Mylesperhr

Sorry, it won't let me go back to retrace the steps, so I can't give precise instructions.  Basically, I went to the Deductions & Credits tab, filled all that out like normal, then when I clicked the continue (or whatever it says) button at the bottom, it analyzes my deductions and, for me, said the standard was the best, but gave me an option at the bottom to itemize anyway.  I clicked the itemize anyway button, then went to the Charitable donations and that's where I saw that it had some donations that I had not entered.  So I deleted those and ensured that any entries that were there were correct (deleted and re-entered).  That was the only method that worked for me. 

If you can't find it, you might try just clicking through all of the Deductions & Credits like you did the first time--that will eventually get you to that analysis page where you are offered the "itemize anyway" button.

Sorry that I can't provide better instructions.
