You can't send a corrected tax return. If your e-file was accepted and you need to make changes, you have to file an amended return. An amended return has to be filed on a special form, Form 1040X. It cannot be e-filed. You have to print it, sign it, and file it by mail. It takes the IRS up to 16 weeks to process an amended return.
