Glad to have you here in the Community, @SuperMarioPowerUp.
Allow me to provide some clarifications about deleting a company file in QuickBooks Online.
Being able to delete your company file on the spot in QBO isn't available. We only allow you to cancel your account. This is to ensure that you can still view your data whenever you need some information when filing your forms for the year.
Your company data will be completely eliminated a year after you cancel it. I'd suggest printing the forms and reports you might need in the future.
To give you more insights on what will happen to your data after the cancellation and on how you can delete a company file and start a new one, you may scan through these links below:
Please know the Community has your back, if you have additional questions. I'll be right here to help. Take care!
