No, I didn't put it on Sch. S, line 16.  The first one I tried that way was only available to paper file.  Then again, that was only a few days after the legislation so it was work arounds on fed and state.

I don't know what to tell you about the payment withdrawal date.  The last few drafts I filed were small amounts that were withdrawn immediately.  I haven't had anyone want to draft in May so far.  I'm just waiting for the calls on the ones that chose April 15 before the extension that want to move the draft date.
