There was no bug. The IRS will not tell you if someone else used your SSN or your child's SSN, bu the IRS does not allow more than one return to be accepted using the same SSN. Someone else may have used your child's SSN by mistake...or on purpose.
If someone else used your child's SSN on a tax return, and your own return was rejected, that rejection came from the IRS. The IRS does not accept another return using the same SSN on it as a dependent. The ONLY way for you to file your return was by mail; a duplicate SSN rejection cannot be overcome. Your fee for using TurboTax was for using the software to prepare a return; it was not for e-filing. The fee for using TurboTax is the same whether you e-file or mail the return to the IRS/state.
