I’ll done all the preparation before trade in of my MacBook Pro but I realized I forgot to unlock and turn off my FileVault. What should I do? Can I just go ahead to send the trade in kit?

If you are providing the Admin password, it's a don't care.
They will re-install whatever they want to have on it. That would be slightly easier if you did a new ERASE of the ENTIRE Device, by immutable device-name (not just the MacOS Volume) taking care to turn OFF FileVault, and then did a new Install.
What you should NOT do is:
Disable FileVault.
Changing the setting takes only a moment. However every block on the disk must be read using on-the-fly decryption, then re-written without encryption. It can literally take days.
