I entered the wrong ovulation when making my account now I can’t chang it

Hi there, thaiwells26-iclo.

Thank you for visiting the QuickBooks Community. I'll be sharing different scenarios and steps to fix it to ensure you're able to back on track as soon as possible. 

Sometimes you need to start fresh with a new QuickBooks Online company. If you're referring to your QuickBooks Online account and your data is less than 60 days, I suggest purging your account. This way, the system deletes all data entered into the company, and you're unable to restore or reverse them. Please keep in mind that this process only works for QuickBooks Online Plus, Essentials, and Advanced. Here's how to purge: 

1. Log in to your QuickBooks Online account.
2. Change the URL to include /purgecompany.
3. Example: URL shows https://...qbo.intuit.com/app/homepage, change to: https://...qbo.intuit.com/app/purgecompany.
4. The next screen will provide a summary of the items to be deleted.
5. Type the word “YES” once the data gets deleted, then click OK.
6. Click Wipe Data once your selections are complete.
7. Once the deletion is complete, you will be rerouted to your home page.

However, if your account is 60 days old or older, you'll need to cancel your account and start a new subscription. You can click this article to view the detailed steps on how to perform the process: Delete your data and start over in QuickBooks Online.

If you're pointing to a manually created account in the Chart of Accounts and unable to change or edit it, I recommend logging in to your QuickBooks account using a private browser. This is to confirm if the cache is the cause why you can't update the account's details. Then, to rule out the possibility of a webpage issue, and private browsing doesn't store local files or cache.

Use these keyboard shortcuts based on the browser you're using: 

• For Firefox or Microsoft Edge, press Ctrl + Shift + P.
• For Chrome, press Ctrl + Shift + N.
• For Safari, hold down Command + Shift + N.

If it works in incognito, I recommend clearing the cache of your regular browser. This removes the history or log of sites so you can start with a clean slate. You can check this article to see the steps: Clear cache and cookies to fix issues when using QuickBooks Online.

If the steps above didn't work, use another supported browser as alternatives.

Lastly, I'm also adding this article to further guide you in effectively managing your business using QBO: Help guide for QuickBooks Online. It contains topics about advanced accounting, banking, and payments to name a few.
