In case you want to delete them all at one time...........
Open your Chrome browser
Look to the top right corner of your browser and click the three dot symbol just below the close option. If you’re having trouble finding the symbol, it should be located next to your Chrome profile picture and to the far right of the search bar where you can type in search terms and web addresses
Hover over the More tools… option until the dropdown appears
Select Clear browsing data… from the dropdown. You can also skip steps 2 and 3 by using a keyboard shortcut (Control + Shift + Delete) from within your Chrome browser. This should load your Chrome Settings in a new tab, with several Basic options ready for use
Click the Advanced tab from the new window. This will load a more detailed list that includes a comprehensive autofill removal option
Check the box next to Autofill form data. Below this option, you should see a brief summary of what will be deleted. If you don’t want to delete anything else, adjust the selections to your preference
Click the Clear data button near the lower right corner
Once that’s done, your Chrome autofill settings should be cleared. That means your problem is gone, but you may have to re-enter a lot of your routine autofill entries. If you want to avoid that, the next method gives you some extra leeway. Using it, you can get rid of what you don’t need while preserving the parts of your autofill data that you’d like to keep.
