How/where do I record "Loss from sale of a business" on my books?
You'll want to create a budget in QuickBooks Online (QBO) so you can record loss from business sale.
Click the Gear icon, then select Budgeting.
Click Add budget.
Enter a budget name in the Name field.
From the Financial Year drop-down, select the financial year for the budget.
Use the Interval drop-down to specify whether the budget is Monthly, Quarterly, or Yearly.
From the Pre-fill data drop-down list, you can choose to automatically enter data from the current or previous year into the budget, and specify the year to use. This is optional.
From the Subdivide by drop-down▼, you can split the budget by Class, Customer, or Location. Then specify which class, customer, or location to add to the budget. This is optional. Note: If you don't see Class or Location options, those settings are not turned on.
