Random deposit into new checking account.

Hello. I’m a recruiter with about 9 years in the marine corps. I recently decided to move my banking from navy fed to SoFi due to their higher yield savings. Today 20240524 I got a deposit for my normal pay to my SoFi account. Don’t know if this was a mistake on the military’s accounting process or I messed something up. Currently trying to ensure I don’t owe Uncle Sam any money down the road lol
