Can Quickbooks stop adding new supplier automatically? I do not want this function.

I appreciate you taking the time to raise your concern here, @sandy107. Know that we only wish you to experience the best kind of service while using the program. Let me share some information about downloading bank transactions into your account.

One of the possible reasons why QuickBooks Online (QBO) auto-fills the transaction fields is that you may have enabled the Automation option in your bank transactions. To ensure that this gets sorted out, I suggest making the feature disabled. Let me guide you through the steps on how:

1. Click Transactions on the left side menu.
2. Choose Bank Transactions.
3. Tick the Gear icon on the right-side menu.
4. Toggle the Add new vendor option under Automation.
