Plz help me finish my taxes I'm trying to claim my child so I'm stuck now I'm disabled and I paid rent the whole year

Where are you stuck?  Do you have taxable income to enter?  What income are you putting in?  The child-related credits are based on income earned from working---so if you did not work then you cannot get child tax credit, etc. 

And for rent:

RENT

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.
