Some states allow it to be done differently, but other states require the same method be used as you used on the Federal tax return, so it depends on what state you are filing.
____
IF your state allows them to be different, the software will "usually" deal with it automatically. i.e. you enter all your possible itemized deductions in the Federal section, and whichever ones the state can use will automatically be transferred to the state's software....and if the "State" itemized deductions is greater than the state Std Deduction, then the software will use the larger one, even if the Std Ded was used on the Federal tax return.
Occasionally, there are a few deductions that a state may allow that the Feds do not...if that is the case, and if there is no itemized deduction entry in the Federal section for that state deduction, then there is usually a place in the State interview where you can add it in.
But there is a huge difference between the software for all the various states, and the interview and progression in the software will depend on what stare is involved.
