Hello @CaliberOne11. I'll help you how to alter your company in QuickBooks Desktop.
You can duplicate an existing company file and add the same vendors, customer contact information, chart of accounts, and lists to make a new one.
For detailed troubleshooting methods on how to establish a new company file from an existing company file, see this article: Create a new company file by copying an existing one.
The other option is to export the data from the original company file and import them to your new account. This way you have to enter all the data manually.
Furthermore, you can still access W2's from the old company. Please keep in mind that you're unable to export it since the form is system-generated.
Additionally, see this article to learn more about exporting and importing limitations in QuickBooks Desktop.
I'm sure that this will put you on the correct track. Please let me know if you have any further questions; I'm always happy to assist. I wish you the best of luck.
