Mistake in return

We have made e filing of  our Income Tax return for the Asst Year 2007-08 i.e., Accounting year 2006-07--In the return for 115jb Schedule of Mat computation - Dividend income received from other company is shown under additions instead of deductions-Due to this tax liability is coming under MAT as per order passed u/s 143(1)-Order copy passed under section 143(1) is not received by the assessee-

Issues:

1)Is it necessary to file the revised return to show the dividend income under deductions instead of under additions-since time for filing revised return is over what is the remedy the assessee has

2)Since 143(1) order is not received by assessee-Inspector says give a letter for order copy? Can we give a letter for order copy

Thanks in advance
