Claiming housing on tax when self employed

I am licensed minister in wash. DC. I am attending Seminary in another state. I need to attain housing to attend school full time.

I am not employed at a church.

I pay rent for a room which I occupy 3 days a week to attend classes. Can I claim the rental expense and utilities on my individual tax return? How do I go about that? And what forms do I use?

Can you recommend a tax agent or company in dc area? Thank you
