Hi Debbie,

I understand your frustration with the auto-fill feature in the Save As dialog box. This is actually a Microsoft feature that is designed to help you save time by suggesting file names based on what you've typed before or what's already in the folder you're saving to. However, I can definitely help you turn this feature off if you'd like.

Here's how to disable the auto-fill feature in the Save As dialog box:

1. Open Excel and click on the File tab in the ribbon.
2. Click on Options at the bottom of the left-hand menu.
3. In the Excel Options dialog box, click on the Save tab.
4. Under the Save workbooks section, you'll see a checkbox labeled "Don't show the Backstage when opening or saving files." Make sure this box is unchecked.
5. Click on the OK button to save your changes and close the Excel Options dialog box.
6. Now when you go to save a file using the Save As dialog box, you should no longer see the auto-fill feature.

Let me know if you have any other questions or if there's anything else I can assist you with.
