I am missing 2 months of transactions from my bank - how do I retrieve?

Download any file formats (e.g qbo, csv) from your bank and import it manually. Otherwise, utilize MT Online as a workaround. It is designed to import into any bank or credit card in QuickBooks Online, so there is no specific setting needed.

Thank you for posting here in the Community, @anakru.

I'm here to help you retrieve the missing transactions from your bank.

Connecting your bank to QuickBooks Online automatically downloads the latest transactions from the last 90 days. Since you want to get the transactions from last February and March, which is beyond 90 days, you can manually upload the transactions. I'll walk you through the steps.

Here's how:

1. From the left menu, select Bookkeeping Transactions, then select Bank transactions.
2. Choose the blue tile for the account you want to upload the transactions.
3. Click Upload from file from the dropdown menu next to the Link account▼.
4. Select Browse and then choose the file you downloaded from your bank. Then select Next.
5. In the QuickBooks account ▼ dropdown, click the account where you want to upload the transactions. Then select Next.
6. Follow the onscreen steps to match the columns on the file with the correct fields in QuickBooks. Then select Next.
7. Choose the transactions you would like to import. Then select Next.
8. Hit Yes.
9. Then, click Let's go.

Also, I recommend checking more information to manually import transactions from your bank or credit cards into QuickBooks Online.

Then, it's time to categorize and match your transactions now that they are in QuickBooks. After you review the transactions, they will show to your accounts.

Let me know how it goes by clicking the Reply button below. I'll be around to help if you have any other questions about downloading bank transactions. Have a good one.
