You can only file one tax return on each account using the online product. A new account must be created for each person filing a tax return.
Each tax filer can only file one return. If you left information off your original return, you can't file another return to enter it. You must prepare, print, sign and mail an amended return form 1040X to make any changes to your original return that has been filed and accepted. Post back if you are in this situation for more information about amending a return.
