I'm happy to see you here in Community, @makemyday24hrs.
My colleague already provided a great response to the question that you've posted. You can refer to this link to see what they suggested doing in this situation: What if my contractor email address is already taken?
Please know that my doors are always open to help you with any QuickBooks Online concerns. Just post your question here, and I'll get it taken care of. Have a lovely day!
