Since you already put his SSN into the system by claiming him, he cannot e-file this year at all. It will do him no good to wait for you to amend. His own return can only be filed by printing, signing and mailing it in now. Your own amended return will take months to be processed and will never "catch up" in order for your son to e-file.
When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s. Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS/state received the return.
Federal and state returns must be in separate envelopes and they are mailed to different addresses. Read the mailing instructions that print with your tax return carefully so you mail them to the right addresses.
