Lic commission return filing in itr 3

In computation window for the A.Y 2019-20, in TDS row, they are added extra column : HEAD OF INCOME.  If we select Head of income Income from other sources for Insurance commission, is there any mismatch for Refunds.  pls suggest.

Another doubt:

If we file ITR 3 for LIC commission income, in Commission without maintaining books of accounts under special business cases, it is mandatory to fill detailed Profit & loss account? If not filled, is there any chance to invalidate the return? pls suggest
