Schedule FA clarification

 here are some general insights: -

Since you've already declared the foreign stock transactions in Table D of Schedule FA, you've complied with the basic requirement. - The omission of stock broker account details in Table A2 might be considered a minor oversight, especially if you've consistently filed your ITRs without any issues. -

Filing ITR-U or rectification might not be necessary, as the transactions are already declared, and you haven't received any notices from the Income Tax Department. 

However, to be on the safe side, consider the following options: 

1. Consult a tax professional or chartered accountant to review your case and provide personalized advice.

 2. If advised, file ITR-U or rectification to declare the stock broker account details in Table A2 and A3 for previous years.

3. Ensure you maintain accurate records and documentation for future reference.
