Usually, it is best to let Turbotax decide for you. Do you have any specific concerns with your tax return?
Note that some states may only allow you to take the standard deduction if you took the standard deduction on federal. Suppose (as a completely hypothetical situation) that the standard deduction in your state for single is is $8000, the federal standard deduction for single is $13,850, and your qualified itemized deductions are $11,000. It could be possible that taking the federal itemized deduction lowers your deduction and raises your federal tax, but allows you to take the state itemized deduction which raises your deductions and lowers your state tax. A person might come out slightly ahead one way or the other, and Turbotax may not test that exact situation for you. (Of course, if your itemized deductions are lower than $8000, then standard is better for both, and more than $13,850 itemized is better for both.)
But we would need to know which state, what their law is on itemized versus standard deductions, and what your tax situation is.
