We rented out our basement for the first time in 2017. Need help determining how to calculate deductions?

Rented out as an apartment?  Or for something else?

Rented as apartment.  FYI apt. is 1/3 of total livable space of house

Is it separately metered for utilities?

No!  FYI Only one person lives down there and my wife and I upstairs so it's 1/3 occupants also.

Does it have its own bathroom and kitchen?  Do you have a signed lease, and is rented at Fair Market Rent?

Is there a simple formula for depreciation?

Yes! It has it's own full bathroom, kitchen with oven and washer and dryer

No signed lease and at the low end of fair market value

It has it's own outside entrance also.

Is there any way to talk to someone on the phone about this?
