How can I return my purchased Apple Gift Card?
I bought a card by mistake now I have to return it

You cannot unless it is a digital gift card that has not been sent yet. See Gift apps, media, and more from Apple - Apple Support
If it is a physical card:
Returns & Refunds - Shopping Help - Apple
“There are some items, however, that are ineligible for return, including:”
“Apple Gift Cards (includes previous generation Apple Store Gift Cards and App Store & iTunes Gift Cards)”
