It's great to see you here, AnDaulton.
We're unable to merge two QuickBooks Online accounts. I would suggest calling us so we can help with the access. Then, import the list of customers, vendors, Chart of Accounts, and products and services from the old account to the new one. Here's a link to get our contact details: Get Help With QuickBooks Online.
Then, follow this guide article on how to import lists: Export Then Import List Data Into QuickBooks Online.
Paychecks, bills, invoices, and other types of transactions can be re-created. You might also want to enter them as journal entries so you can lump sum the amounts.
You can also look for third-party applications that offer exporting/importing transactions between QBO companies. You can find them here: https://apps.intuit.com.
