If you have no other income you DO NOT need to file. SS or SSDI or ssi is not taxable at all. It is only partially taxable if you have Other income above the amounts listed. And there is no benefit in claiming deductions or credits or dependents.
SS Benefits is not Wages. Wages are only from jobs where you get a W2.
You only get a Refund if you have withholding taken out from W2 wages or from other kinds of 1099 income.
You do not need to file every year. Only if you have income to report. The IRS doesn't care. If you want to file a return for some reason you will have to print and mail it. Or you can enter $1 of fake interest to let you efile. You could get a blank 1040 form and enter all zeros on it.
