QB Issue Resolution:
Once inventory tracking is enabled on your QBO account, when creating an inventory adjustment, QuickBooks automatically creates the Inventory Shrinkage account. This is how QBO works and it is part of the QBO feature.
If you wish to select another account when creating adjustment, you can simply click on the drop-down arrow under Inventory adjustment account and select the correct account you want.
