I found my late grandpa’s bank statement from 2012 with a modest amount, naming me as the “In Trust For”. What should I do?

Summary

I was finally going through some papers while declutterring and found an old statement listing me and my sister as the ITFs. It is from Talmer Bank and Trust in Port Huron Michigan but that bank doesn’t exist anymore. seems to have been absorbed by Huntington. other notes: it was a dormancy notice saying it was inactive for 12 months and to call to restore its status. i am not sure if that was done or not. It says there was about $4,000 in the account, “classic savings”. Not sure if anything is
