How to use steam gift cards / wallet codes

[In Lobby - Competitive 21/2/23]

i went to the website to check and all they told me was:

Pick up the gift card which has the dollar amount you would like to purchase.
Take to the check out. Once paid for, it will be activated and loaded with the value printed on the front of the card.
When you get home scratch the gray security bar on the back of the card to reveal the 15-digit code.
Log into your Steam account (or make one if you don't have one) and go to "Redeem a Steam Wallet Code"
In the resulting screen enter your code into the “Steam Wallet Code” field.
Click Continue.
Now you will have the amount of denomination of the gift card added to your Steam Wallet which is viewable in the upper right corner of Steam.

problem is, how to go to "Redeem a Steam Wallet Code" thingy? pls help

Can I use a gift card that isn't a steam gift card?

This is what I wanna know, do prepaid Visa/Mastercard cards work?
