It says a standard deduction of $6,350 is recommended for me but I didn't have any expenses in 2017 to have a deduction in the first place. Why do I have a deduction?

I worked out of state for one job in 2017, not sure if that is a reason why I have a tax deduction all of sudden or not?? My federal refund is said to be $466 as of now, it says it is still in progress though, so it may be subject to change??..
