Hello there, @hayerkaiser.
Changing the Master Admin on the account depends on who's paying the subscription to Intuit. And I'd like to share it with you and help you from there.
If your accountant is the one paying the subscription, you'll have to contact him/her. This way, he/she can help you transfer the Master Admin rights of your account.
However, if you personally pay your subscription, I suggest contacting our Technical Support Team. Agents have the necessary tools to help you transfer the Master Admin rights.
To reach them, you can follow the steps provided by MorganB above.
In case you want to change the email address you use to sign in, you can read this article for your future reference: Update or change your Intuit Account sign-in information.
Please know that you can always get back to this post if you have any other questions. The Community team and I are always here to help.
