No, a spouse can not be a dependent. You list yourself as spouse and you get a personal exemption for that.See page 11 of IRS Publication 501 which says:“Your spouse is never considered your dependent.”You can find IRS Pub 501 at this link:https://www.irs.gov/pub/irs-pdf/p501.pdf
There's another question in the persoanl info section that asks if someone else, other than you spouse, can claim you as a dependent. Answer NO, unless you know, for sure, that someone, like your parents, will be claiming you.
