How do i get my rent deposit back?

i rented a house for 1 year.i put up $1100.00 security deposit.the landlord and i did a post walk through of the house.she found little things like 2 cracked tile ,small hole in drywall caused by the door knob.old closet door does not slide closed properly.i gave her 60 days before i called to inquire about my money.she sent me a suspicious looking bill saying that it cost her $700.00 to repair her home . i do not agree .what are my options.
