If you accidentally filed your taxes wrong, you can correct them by going to the IRS website and clicking on the "File Your Taxes" link. Once you click on this link, you will be taken to a page where you can enter your information in a form called a "Form 8-K." You will also need to provide your taxpayer identification number (TIN) and your social security number (SSN). The IRS will then send you a letter telling you how to correct your taxes.
