"Re: How do I elect to itemize? Box bottom of Schedule A does not accept input."

The program will default to whichever is higher, itemized or standard.   You cant just type a number at the bottom of Sch A, you need to fill out Sch A and it will put the total in the bottom box.

If you want to itemize even if the standard deduction is higher, I think theres a box to check somewhere on the Federal Information worksheet.   (Ive never had to check it, but I know Ive seen it)
