State tax filing

One last question- If I was filing 1040, I could either claim standard deduction or an itemized deduction. The sales tax on my car in Washington state is $5600 . However, the standard deduction allowed for a single person is $6350 in 2017. I won't have to file state taxes in WA. If I can claim only one of those, so in this case clearly the standard deduction is a better option, right?
