Where am I able to enter that my Spouse is a Student? Or does it not matter? Thank you.

It might matter for the Child Care Credit.

In the Personal Information, when asked her Occupation, you can put Student. 

Otherwise, for taxes it will only trigger questions that might be beneficial to claim certain credits, such as the Education Credit or Child and Dependent Care Credit.

Your spouse is your joint filer on your tax return, not a dependent.
