Thanks for coming by, @squirrelfoodsand.
I have some information about changing your email address. Since you've corrected your email address right away, it'll take effect the moment our system will recognize it.
However, if you're changing it via the change request form, it'll take 3-4 business hours (8 AM – 5 PM PT). After that, you'll get an email from firstname.lastname@example.org with the next steps.
Here's an article that contains details about it: Change your email, user ID, or password for QuickBooks Online.
If you need help with other tasks in QBO, click this link to go to our general topics with articles. Just look for responses that fit your concern.
Keep me posted if you still have questions or concerns with your account. I'm always here for you. Take care and have a fantastic weekend ahead.
