Q: Hi guys! can you please help me Where can I found airdrop? airdrop is not showing on my control center. please, thanks!

Do you have both Wifi and Bluetooth on?

For Airdrop to appear, there has to be a compatible  iOS or OS X device within range (Bluetooth range to establish connection)

Use AirDrop to send content from your Mac - Apple Support

I don't think that is correct, it should show up in Control Center on an iPhone showing either Contacts or Everyone.

Check your restrictions if airdrop doesn't show in control center

i had the same issue, just reboot the devices you are trying to connect and then you are good to go.
