where to inbound the ball after timeouts

[tjlref]

New to officiating, trying some 7th and 8th grade games.
Tonight the coach from one of the teams tells me that the ball should always be inbounded from the division line after a timeout.

Looking at the rule book, it does not seem to be clear.

After a violation the ball should be inbounded closest to where the violation occurred, so if a team calls timeout on the dead ball, shouldn't it go back to spot of the original violation??

Please help me on this one.

Thanks
