do I have to show IRS statements as proof of ID as part of app. 4 protected trasferee W/ medicade

You should be able to remain in the house, and to have the house transferred to you under the "Care-giver child" exemption.  You will have to prove that you lived in the house for at least two years prior to the transfer, and that during that time you cared for your mother.  the care has to be pretty specific, simply transporting her to doctor's visits, or shopping is not sufficient.  You will need to get a doctor's statement that the care you provided for your mom allowed her to live at home, and without that care, she would have had to go to a nursing home.
