I’m having trouble accessing my 2022-2023 accounts, I need to get it all done by January 31st.

Thank you for bringing this to our attention, kirstyh82.

I completely understand how frustrating it can be to lose important data like this, especially when it comes to tax returns. I'm here to help and get this sorted out for you. 

To begin, have you tried checking the Excluded tab in QuickBooks Online? Transactions that have been excluded will not show up in your account records or financial reports, but they can still be found in the Excluded tab. If the entries are there, you can simply undo them, and they will reappear in your account records. 

Here's how:

1. Head to the Transactions menu on the left panel and select Bank transactions.
2. Go to the Excluded tab and look for the entries you're working on. 
3. Click the Undo option and the transaction moves back to the For Review tab.

For in-depth information on what happened to deleted or excluded downloaded data, refer to this article: Exclude a bank transaction you downloaded into QuickBooks Online.

In the event the account is disconnected from your bank feeds, you'll have to reconnect it to bring the entries back into your company. To add the missing data, download the file from your bank's website and manually import the transactions into the program. This guide will walk you through the process: Manually upload transactions into QuickBooks Online.

Once you've added the bank data to the company, categorize them to the correct account to ensure you can reconcile it seamlessly. To speed up the process of classifying transactions, browse through this article for the complete details: Set up bank rules to categorize online banking transactions.

If you're using QuickBooks Self-Employed (QBSE) and unlinked the online banking connection, the transactions will no longer show on the Transactions page. Let's connect your account to the bank feeds and then categorize them so they'll tracked into the correct line of your Schedule C. For entries that are beyond 90 days, upload them manually via a CSV file.

I've included some resources that tackle processing a tax return using the online version and QBSE as well as steps to handle tax payments and refunds:

•  Submit a MTD for VAT Return to HMRC
• Record a VAT payment or refund
• Self Assessment for Income Tax checklist for QuickBooks Online
