I feel a bit embarrassed to ask this but when you hand over something banned before getting on a plane, what verb should you use? Like, 'surrender' or 'give up'? And, speaking of it, what do you call those places at airports where your luggage is scanned, you're frisked down, etc.?
Surrendered is a good option but may also convey that the action was taken with some hesitation.
She surrendered the bottle of wine to the agent, displeased that customs cared about such a frivolous item.
If you have the flexibility, I would change the subject of your sentence.
The TSA agent confiscated the nail clippers I had forgotten in my bag.
Confiscate: appropriated by the government, forfeited
As for the place, the TSA calls it Security Screening, but just security is understandable enough in context.
I can accompany you as far as security, but then I will have to say goodbye.
