Do I have to file while collecting disability?

It depends on the type of disability and how much.

 

If you are getting SSDI and that is your only source of income you do not need to file a return.  

 

If you are getting disability from an employer sponsored plan and you received a W-2 for the disability, then yes, you would need to file a return if you received more than $14,600,

 

Check if you need to file a tax return

 

 

There is not a rent deduction or credit on your Federal return.  If your state has anything for renters you will be prompted to enter your rent info when you complete your state return.  As far as I know, the states that have anything for rent are Arizona, California, Connecticut, Hawaii, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Jersey, New York, Rhode Island, Vermont, Washington DC, and Wisconsin.
