Should I add my 1098 form for primary home used to rent rooms while also co habitating the house?

You can, if your total itemized expenses will be greater than your standard deduction. but you will need to allocate a portion of the interest to you and the rest to the rental rooms.  So if your house if 2,000 sq. ft. and you rent out 1,000 sq. ft. you would claim half the interest as an itemized expense and the other half as a rental expense.
