WHY and which ITR just to declare company shares ?

The tax department may have noticed a mismatch because the shares (or their gains) should be reported even if they are not yet materialised or transferred to your bank. The department expects all income, including unrealised gains on investments, to be disclosed if they are taxable in the assessment year. 

Yes. You need to revise the return if the original filing missed declaring the income related to those shares. Unmaterialised gains are generally not taxable until realised, but you must report the transaction details and any applicable capital gains in the year of redemption or transfer. 

File the apppropriate ITR form applicable to your income status (usually ITR-2 or ITR -3 for individuals with capital gains). 

Declare the shares under Schedule CG (capital gains) if there is a capital gain on redemption, or under the relevant income schedule if the shares are considered income.

Refer to Section 45 of the Income Tax Act for capital gains on transfer of shares and ensure compliance with reporting requirements in the revised return.
