if you are trying to file for 2021, then just paper file The IRS will figure it out
for the future, set up a PIN. With a PIN, only the person who knows the PIN (presumably only you) can efile using your childs SSN.
if the return is paper filed without the PIN, it is going to go through a lot of scrutiny because the IRS knows there should have been a PIN and the more likely case is you efiled return will have been processed before the paper return in any event.
