Hi Mahlon,
In Method:New to find the "Delete from Method" option, please follow the steps below:
go to Gear > Preferences > Quickbooks > "Sync Conflicts" > "View Sync Conflicts" > select all the conflicts you want to delete and at the bottom of the screen will be the option "Delete from Method".
If there are no sync conflicts, you will not be able to go beyond "Sync Conflicts".
Try it out and let me know if this helps.
