On review of irs.gov pertaining to the covid stimulus, I note the following:

"IR-2020-61, March 30, 2020

WASHINGTON — The Treasury Department and the Internal Revenue Service today announced that distribution of economic impact payments will begin in the next three weeks and will be distributed automatically, with no action required for most people. However, some seniors and others who typically do not file returns will need to submit a simple tax return to receive the stimulus payment."

My problem is, I have been unable to e-file for clients who receive only ss benefits.  How can I e-file returns to insure my senior clients (I have not prepared taxes for in over 2 years)  will receive the stimulus as indicated above?

Thank you,
