I did an indirect rollover from my traditional ira to my checking account but had a change in mind. i returned the money back to the original ira. is this a taxable event

No, returning the funds back to the same account would not be a taxable event.

However, the funds must be returned within 60 days of the distribution and they must have been returned in their entirety.  For example, if you received a distribution of $1000, but $200 was withheld for taxes, you must return the full $1000 to have a non-taxable event. 

So is this considered an indirect rollover transaction? I ask because I only get to do one indirect rollover in a 12 month period.

Yes, it would be considered an indirect rollover.
