Since
you have already filed your return, you'll need to wait for your tax
return to either be rejected or accepted, if
it is rejected you can make any corrections or add
any information that you need to add, correct any other errors on the
return and resubmit it.
If it is accepted, you will need to amend
your return to make any corrections or add any information that you
did not include on your original return. You cannot e-file an amended
return as this cannot be filed. You will need to print and mail the amended
return in order to file it.
You will need to amend your prior year tax returns to include her Form 1095-A information.
