Thanks for following up with the Community, Saphire605. I appreciate your detailed information.
 

Since you've received a letter from the Internal Revenue Service (IRS) advising that your Signature Pin Registration doesn't appear to belong to the authorized signer, I'd recommend getting in touch with the IRS directly to confirm what options you have.
 

If you're in need of a tax professional, there's an awesome tool on our site called Find a ProAdvisor. All ProAdvisors listed there are QuickBooks-certified and able to provide helpful insights for driving your business's success.
 

Here's how it works:
 

1. Go to our Find a ProAdvisor page.
2. Use the City or ZIP search field to specify a location.
3. Select Find a ProAdvisor.
4. Browse through your results and find one that works best for the business. You can click on each ProAdvisor's profile to learn more information about them.
   
   

Once you've found an accountant, they can be contacted through their Send a message form:
 

1. Use the available text box to introduce yourself. Be sure to include details about which services you're looking for.
2. Enter your appropriate info in the Your name, Your email, and Your phone number (optional) fields.
3. Hit Send message.

You'll also be able to find many detailed resources about using QuickBooks in our help article archives.
 

I'll be here to help if there's any questions. Have a lovely Tuesday!
