@suesue1A number of practitioners are talking about adding their own questions about EIP.  As for your other question, tax practitioners are not supposed to know anything about their clients' finances - that's what an organizer is for and it is your clients' responsibility to furnish the necessary info to you.

In any case, your clients should have received their Notice 1444 for each EIP.  If they misplace it somehow, they should be able to check the amounts they received at https://www.irs.gov/payments/view-your-tax-account.
