DTS Per Diem deposited in an account that isn’t mine

Feel very dumb for this. Was going through my DTS and GTCC today with admin and discovered that on my DTS there was a random checking account linked for EFT. Based on the routing number it’s a Navy Fed account. I have never had an account with navy fed and I have no idea how this account was put in on my profile.

I don’t use DTS or get per diem too often so this went unnoticed for quite a while. I’m working with my admin department now but wondering if there’s anything additional I should be doing to attempt to get my money back. For all I know this account has been linked for years.
