Thank you for getting back to us, @bow1hunting.

The Action column stated by my colleague JonpriL above can be found on the Custom form styles page. I'll attach a screenshot below for your visual reference.

However, going back to your original concern, you can go to the Account and Settings to turn off the auto numbering function on your sales forms. Here's how:

1. Click the Gear icon, then select Account and Settings.
2. Select Sales from the left menu.
3. Go to the Sales form content section and toggle the Custom transaction numbers to turn off the automatic numbering.
4. Hit Save, then Done.

Also, the functionality of this option is discussed by my colleague MadelynC above.
