Get your taxes done using TurboTax

You would enter your itemized deductions on your federal side and it should flow through to your Arkansas tax return.  If after choosing the standard deduction on the federal return, you notice it doesn't flow through to the Arkansas, choose taking itemized deductions (even if far less than standard) for the federal return and go to the state to make sure it flowed. Then go back to the federal and change it to the standard deduction.
