What you see on Sch H and page 2 of Sch SE are only amounts that may be deferred.  You'll see that these amounts don't go anywhere on the return, when these should flow to Sch 3 (if deferral is elected).

If your client would like to defer these payroll taxes, you need to make the input under Taxes > Other Taxes > Self-Employment Tax (Schedule SE) and check the box for Elect to defer maximum allowed amount of Schedule SE or H taxes to 12/31/21 or 12/31/22.

You may like to refer to this other discussion for a more in-depth explanation:
