If there is nothing else that requires you to file a tax return, then this would be the only form of information for the IRS to go by in order to determine what you are due for stimulus (for 1st, 2nd, and 3rd payments) so I would definitely file a tax return if you have not done so already. Provide the IRS (via the tax software) your bank information if you do not receive your SS checks via direct deposit. If you do get direct deposit then the IRS should already have this information. However, just to be on the safe side I would file a return.
