Yes, you are. Any estimated tax payments you made for the state will still be deducted on your state return, as part of your payment for 2018 tax. For the Federal, though, the only way to deduct state tax is to itemize deductions. If you take the standard deduction then you have no deduction for state taxes on your federal return. That can be a good thing next year because, if you receive a state tax refund for 2018, it will not be taxable in 2019.
