How can I file last years 2007 and add my other w'2s from last year I received late.. from moving.. I filled one I did recive! But I recently received the last two how do I file them?

For amending your tax return, you must file IRS Form 1040-X. Column A is what was on the original return, Column C is what should have been there (that is corrected amounts) and Column B is the difference. Complete these columns and then refigure your tax.
