To change your firm information:

If you plan to e-file tax returns, you'll need to submit an EFIN verification document in order to change your firm name or address. That's because the firm information in your software must match the information on your EFIN Application Summary from the IRS. Update your information with the IRS prior to submitting a firm information change to Intuit. Then, follow the steps to verify your EFIN, and your firm information will be updated accordingly.
