Since you and I cannot really do that and keep clients, you might try running an article or two for your client. I've found one that seems clear for this purpose: https://www.thepennyhoarder.com/taxes/child-coronavirus-stimulus/
Also, the number given in the letter IRS sent out, Notice 1444: 1-800-919-9835
I just got off the phone with a caller, who's not even a client, and I gave her that number. She was so appreciative and said, "Now I know why my brother brags on you all the time." So, her brother is a client. Yeah, I know, but I was glad I tried to help her.
