I can share different ways to remove a location from a transaction, Ashley.
When opening a transaction, find the Location field and click the Backspace on your keyboard to empty this box, then Save and close. By doing so, it takes the location off of those transactions.
Additionally, you can inactivate a location if you no longer need or use it. This process is the same as with deletion. Follow the steps below.
Go to Settings and select All lists.
Click Locations.
Pick the location you want to delete, then from the ▼ dropdown menu in the Action column, choose Make inactive.
