Once it is established that the return was submitted, then check these overview rules listed below when filing for someone who is deceased. If you need to amend, start with this resource: How do I amend(change or correct) a filed return?
If it was not electronically filed, see When a tax return can't be e-filed no matter what you do

How to file a return for someone who is deceased:
Federal:
Your mother will still use the filing status of married filing joint for 2019.
Hopefully, you added Form 1310, which is used to establish you as your husband's personal representative. As long as the Social Security Administration has already been notified of the taxpayer's death, you can proceed with the filing.

You do not need to attach a death certificate to the tax return. Instead, keep it for your records and provide it if requested.
IRS Resource: 2019 Publication 559: Survivors, Executors, and Administrators
State:
It depends on your specific state what form would be required. I recommend checking with the state individual income tax filing instructions. Some states would require a certificate showing your appointment, while other states have their own Form 1310, for example.
Click the link to find out How do I contact my state Department of Revenue? Form 1310 is needed for the federal filing when you are identifying yourself as the personal representative, but there may be a different requirement for your state.
Regarding the stimulus payments, until the 2019 tax return is filed, the IRS will be using the 2018 tax return filed. Your mother will receive $2,400 if she qualifies even though your father has passed away. She will not need to pay back his portion.
