Greetings @scott-travis36
Great news! You can add data to your company file, with any dates, as long as you have not closed the books for the previous years. If you have closed the books and need to make edits, here are the steps:
- Sign in to QuickBooks Online as a master or company admin. Only admins can make these changes.
- Go to Settings ⚙ .
- Then Accounts and Settings.
- Select the Advanced tab.
- Then Edit ✎ in the Accounting section.
- Change the closing date.
- Save and then Done.
I’m including an article with more details for your convenience: Edit your closed books
An important detail to note: Although you can enter data and run reports for tax purposes, any tax filings would need to be done outside of QuickBooks since the tax periods have closed.
You’re all set! Let me know if you have any additional questions about entering your data, or anything else. I’ll be here.
