Hi there, Mary.
If you received an email indicating that you need to update your credit card information for QuickBooks Desktop (QBDT), it is essential to verify the email's legitimacy before proceeding.
You can log in to your Intuit account through the official website https://accounts.intuit.com.
Then, navigate to the Product and Billing section, as mentioned in the email.
Input the new card number, expiration date, and CVV code, even though the number may remain the same on a replacement card.
You can check these article for more info on updating account details:
If you have additional questions, please reply to this post.
