@clippinchick Don't be so hard on yourself. Just learn and move on.
Know that QB will never call, unless you request support to do so. Be careful with emails, as well. Even with the email address that Intuit/ QB team will tell you is good, you could still get scammed. To contact QB, use the link within your account. Never go off of what Google might have. Most of those are suspicious.
I'm sorry you got scammed. I would change the card, just to be safe.
Good luck.
