Clarification on re-investment of LTCG amount from Equity MF redeemed during FY 2021-22 [AY2022-23] to save Tax.

I am a retired professional and have been filing the returns under ‘old tax regime’ to claim the benefits of deductions u/s 80C, 80D, 80TTB, Standard Deduction, etc.

I had purchased the units of equity oriented close-ended mutual fund on April 11, 2018 with a lock-in period of 1300 days i.e., > 3years, which I have automatically redeemed after the lock-in period; and the redemption proceeds [deposit amount plus the Long-Term Capital Gain] have been received on Nov 1, 2021. The total LTCG gain is of more than Rs 100,000.

I understand that out of total LTCG gain an amount of Rs 100,000 will be fully exempted from the tax, and only the balance amount will be subjected to tax @10% plus cess without indexation. Kindly confirm.

Since this has been my first time investing in such a scheme, I am not well versed. 

I hope you will look into the above queries and will arrange to provide the answers at the earliest, in order to make the investment in the Bond well within the time-limit up to 30th March 2022, and to avoid last day rush. Further, since the amount has been received in 1st week of Nov 2021, can it be invested till 30th April 2022 i.e., within 6 months from the date of receipt to get the tax relief against FY 2021-22 or shall it be invested before 31st March 2022?
