Transfering my own money from Spain to my US account

Hi there,

My spouse and I lived and worked in Spain before moving the US and we want to transfer our 40K EUR that we still have in our bank account in Spain to our US bank account?
I understand I do not need to pay taxes since it's my own money and I've declared my accounts abroad with the FBAR, but do I need to report the transaction somehow?

Thank you.
