I am trying to enter a vendor but it says it has previously been entered but it is not on my vender list

Before creating a new vendor, verify if a vendor with the same name or display name already exists, as duplicates cannot be saved. Let me break this down in detail, Laura. 

If there's an existing display name, creating a new one with the same information will not be possible, as you'll be prompted to enter a different display name. Additionally, there may be instances when other vendor names are placed on the next page, preventing you from seeing them on the first page. 

With this, we can use the search bar located at the top of the Vendor column to locate existing vendor names without scrolling or switching to another page. If it is confirmed that there's no existing name and you still cannot create a new vendor, let’s use your private browser to determine if the problem is related to your standard browser settings or data.

Here are the shortcut keys for accessing private browsers:

• Google Chrome: press Ctrl + Shift + N
• Mozilla Firefox: press Ctrl + Shift + P
• Microsoft Edge: press Ctrl + Shift + N
• Safari: press Command + Shift + N

After using your private browser, let's create a new vendor again by following these steps: 

1. Log in to your QBO account. 
2. Go to the Expenses menu, then click the New Vendor. 
3. Enter the Company name and/or the Vendor display name from the given fields. 
4. Fill out other fields if needed. 
5. Review every details you've entered. 
6. Once you're done entering the vendor's details, click Save. 

Furthermore, you can run a Vendor Contact List report to view all of your vendor's list and their corresponding information.

Please let me know if you have additional questions or information regarding creating a vendor, Laural. I'll be around to help you in any way I can.
