Turnover not shown in GTSR -3B want to add and pay in GSTR 9

Yes — add the missed turnover in GSTR-9 Table 4, let GSTR-9 compute the extra tax in Table 9, and then pay that tax via DRC-03 selecting “Annual Return 44”.
If applicable, disclose the adjustment in GSTR-9C.

Yes—if the omitted ₹1,00,000 is taxable outward turnover, report it in GSTR-9 Table 4B if it is a B2C taxable supply, with the applicable tax in the corresponding tax columns. Do not use Table 4B merely because the turnover was omitted from GSTR-3B: classify it by the actual nature of the supply. GSTR-9 is an annual reconciliation; it does not itself revise the GSTR-3B liability.

Pay the additional tax and applicable interest through DRC-03, selecting the annual-return-related reason applicable on the portal. Do not alter Table 9 to imply tax was paid through GSTR-3B; Table 9 reports tax paid as per returns. Disclose the additional liability and payment in the relevant GSTR-9 fields, including Table 14 where applicable. GSTR-9C should reconcile the turnover and liability if you are required to file it; it is not a substitute for reporting or paying the liability. The exact table treatment depends on whether the ₹1,00,000 is taxable, exempt, zero-rated, or otherwise classified.
