thank you! super helpful! For the ones who wants a more precise instruction: go to Tools-->Topic List-->Scroll down to "Standard Deduction v.s Itemized Deduction" then click on that topic.
It will led you to the page where you can choose which one to select.
For my case, my first calculation probably mistakenly selected "standard", then I can't figure out where I can change back by following TurboTax suggested procedure. I even switched to Form and still not letting me checkbox for Itemized. But the procedure above works!
