Deductions & credits

Thank you for your reply.  My issue (which I didn't adequately explain in my question) is that I had already completed my Fed return using the SD and had moved on to the state return....which meant I had moved past the screen that gave me the option to change from the FED SD to itemized deductions.  When I realized that the huge increase in state taxes over the previous year was due to the using the SD, I tried to change the Fed option but could find no way to do that.  So I bit the bullet and paid for help from a live agent.  She was absolutely fantastic!  It still took over an hour on the phone for us to get to where I needed to be to change the Fed deduction.  But it was well worth the time and extra $$ for what it saved me in state taxes!  What I have learned over the years of using TurboTax is that it's very difficult, if not impossible, to change options once they've been selected without starting the return all over again.  TurboTax techy programming people....you need to do better!
