Why do you need to file a return? What income do you have?
If you only get SS it is not taxable and you do not have to file a return. And there is no benefit in claiming dependents or deductions. And you can't efile a return with no taxable income. If you want to file you will have to print and mail it. Or you can try adding $1 of interest to let you efile. Make up a fake 1099Int.
