I think I got scammed

Thanks for sharing. It happens. I hope you don't get hassled any further. I uploaded your first post to duck.ai (anonymous and private) and asked for followup steps. Here's its response:

Good steps so far. Next actions (prioritize):

1. Contact your bank immediately by phone using the number on their official website or your statement. Tell them you may have been scammed, confirm the check was canceled, and ask them to:
   • Put a fraud/security alert on the account.
   • Reverse or block any unauthorized transactions.
   • Freeze or close the account and issue a new account number and debit/ATM card if any credentials were exposed.
2. Contact Quicken support using contact info from Quicken’s official site and explain the incident. Ask whether any changes were made to your Quicken account, and request steps to secure or restore it.
3. Report the fraudulent charge(s):
   • If the $599.99 was charged to a card, dispute it with the card issuer immediately.
   • If paid by bank transfer or check, tell the bank and request a stop/payment reversal if possible.
4. Scan for and remove remote-access software and malware:
   • Check for and uninstall remote-access apps you didn’t install (e.g., AnyDesk, TeamViewer, LogMeIn, Bomgar, Chrome Remote Desktop).
   • Run a full macOS anti-malware scan with a reputable mac scanner (Malwarebytes for Mac or similar).
   • If you’re unsure what was changed, consider restoring from a known-good Time Machine backup or reinstalling macOS.
5. Revoke remote-access and credentials:
   • Change passwords again for bank, Quicken, email, and any other sensitive accounts—use strong, unique passwords.
   • Enable two-factor authentication (2FA) on all accounts that support it; prefer an authenticator app or hardware key over SMS.
   • Check and remove any unknown user accounts or new admin accounts on the Mac.
6. Check for identity theft or account takeover signs:
   • Review recent bank and credit-card statements and Quicken transaction history for unauthorized activity.
   • Set up bank/credit alerts for large transactions.
   • Consider placing a fraud alert or credit freeze with major credit bureaus if personal info (SSN, drivers license, full name + DOB) was exposed.
7. Preserve evidence and report the scam:
   • Save screenshots, email/text messages, receipts, and any remote-access logs.
   • Report to your local police (file a report) and get a copy — useful for disputes and chargebacks.
   • Report to appropriate authorities: in the U.S., file a complaint with the FTC (IdentityTheft.gov/complaint) and report to the Internet Crime Complaint Center (IC3) at www.ic3.gov.
   • If paid by credit card, report to the card issuer as fraud and ask for a chargeback.
8. Monitor and follow up:
   • Monitor accounts and credit reports for at least 12 months.
   • Check Quicken for any linked financial institutions or third-party apps that weren’t authorized and remove them.
   • If you shared sensitive documents (checks, scanned ID), contact any institutions on those documents to notify them and request extra monitoring.
