Why did you kill it at that point?

That would be the question you should ask yourself.

You do not need to wait for the ball to be in the circle to kill it. The obvious example is a slide play with the defender holding the tag...

For your play, most likely what would have happened in 2b defender would have looked at 1b and tossed the ball to F1.. and you could kill it and there would be no possibility of questions.

We're likely talking a wait of a few seconds.

I agree, you killed it prematurely, but more importantly, without sufficient cause to kill it.

If it happened that everyone stood there looking at you, almost waiting for you to kill it (for whatever reason) or a coach started giving you cause to go ahead and kill it (sniveling about the obs/DC wanting int)...or whatever, go ahead and kill it and get to addressing the situation.
