Yes, if the return was accepted AND PROCESSED, and you want to file a joint return, then you would need to Amend Your Return submitted to include her income on the return as well.
HOWEVER, if the return was not yet processed, wait until the return is processed as the IRS MIGHT catch the error and make a correction themselves. If they do, you will get a letter in the mail from them telling you that they made a change to your return and you will also get the adjusted refund. If the return is processed without any correction from the IRS, then you will need to file an amended return.
If the state is still pending then you will need to wait until it is accepted or rejected and then if accepted, you will need to amend your state return to include her income. If it is rejected, then you will just need to add her income to the return and resubmit and fix any errors that are on the return.
