I am trying to trade in my car and I need the registration and I can’t find the registration anywhere where can I get it and how long will it take to have a copy of it.

Show the dmv your vehicle title or paperwork for your auto loan if you dont have a title and request duplicate registration. Cost is=$5.00

You can go into the DMV and purchase a copy of the registration. Usually the wait time is around 15 min most days. But it depends on the day and hour you arrive. I think you can even do it online now as well. It's like $2 for the copy.
