Welcome! This forum has a treasure trove of great info – Scouters helping Scouters! Just a heads up, though - all content, information, and opinions shared on this forum are those of the author, not the BSA.
However, she needs to use BSA member ID number 135682865, because that is the one with her registration history and her parent / child relationships (at my.scouting).
Her training should merge within 24 hours. Please let us know if it does not.
@DonaldClark_Jr there is no merging or deleting MIDs really - the users can log into my.scouting.org > Click Manage Member ID > one of the BSA # will be there marked PRIMARY > then add the other MID (BSA #) - you want to make the one that is your registration PRIMARY
If there is a difference between the 2 (like a first name vs. nickname it will fail and we can help - just post both MIDs (BSA#) and we can take a look - the first one the user has already taken care of
