The "Business" tab in the ITR-Individual Tax Return is an area if an individual needs to report an income and expenses for the business.
Note: "LodgeiT doesn't support financial statements or depreciation data allocation among multiple business worksheets. You must do it manually."
LodgeiT automatically fills ITR Business Income & Expense tab with 'QuickBooks Online' financial data, but doesn't fill Business worksheets. Moreover, if any business worksheet is created in ITR then LodgeiT will not fill Business Income & Expense tab. Instead the data for this tab will be taken from business worksheet. Business worksheet data have to be filled manually.
If you want to fill Business Income & Expense tab with 'QuickBooks Online' profit & loss data you need to remove existing business worksheets.
"Add worksheet"" button under Business section is applicable only for clients with multiple businesses and do not import Financials.
