Can Quarterly Estimated Tax payments be e-filed separately from the return if correct box was not checked?

No.  Why not suggest your client to set up and schedule online payments?

The answer was absolutely accurate and concise.  I took it one step further and set up the first quarterly estimate electronic withdrawal with EFTS for my client since it was my error that it didn't get done.  Note: Future quarterly estimate withdrawals must be set up within 30 days of the withdrawals.

NP, @westate1!  Personally, I would hesitate to touch any account that rightfully belongs to a client and not designed to be accessed by third-parties in the absence of official guidelines or clear regulations.
