Did you get a SSA-1099? Do you have any other income?
If you ONLY get SSI or Social Security or Social Security Disability or a SSA-1099 or RRB-1099 for railroad retirement you do not have to file a return. And there is no benefit to itemizing deductions or claiming dependents.
You can file a return to get back any withholding taken out. If they are taking out withholding then you should tell Social Security to stop taking it out.
