I forgot to add a job I only worked at for one month, Am I able to fix it if I've already submitted my forms?

Once the IRS accepts your return you can’t change it. But you can amend it after it has been processed and any tax liability settled.

To add a form once your return has been Accepted, please see this Help Article to Amend a return to add any additional forms.
