I forgot to get the code

When should I do when I forget about the code after the buyer has collected?

You can ask the buyer now to give it to you via message.    If not you will have to wait up to 21 days for the payment to be released.

Have you messaged the buyer and asked them for it?

Without it, you have no proof that they have their item, so they may get a refund if inclined, and your payment will be held for at least 14 days.
