For the most part I suppress the 2210 penalties and let the IRS send a bill anyway.

I would just fudge the 1Q payment date to 4/15.  If the 2210 goes away, you're done.  If not then you can decide what to do next.  I haven't seen many of these but I *think* the way the law reads, the "period of time" between 4/15 and the adjusted disaster due date is disregarded.
