If you
have already filed your returns this year, you can't go back and add the information. You will need to wait to see if
your return is accepted or rejected. If
rejected, you may correct and resubmit. If it is accepted, you will need to file an amendment by mail,
and that will not be ready until mid-February.
You may check your e-file status online here
using only your social security
number and zip code.

1040X finalized, they will appear in this TurboTax FAQ.
If you have not already filed your returns (or when you come back to work in amendment) you may reference the following TurboTax FAQ for how to enter those:
