Can a Sgt do a 6105 entry on a Junior Marine?

My Sgt made me sign a 6105 counseling for being an hour late to work. Im not complaining, as I couldve easily received Article 15. But now I wonder since it was a Sgt and not at least a SNCO, will it go into the system, my ompf, or SRB? Any guidance will be greatly appreciated. Thanks.
