I'd be happy to assist you with bringing your transactions into QuickBooks Online (QBO), Robinson.

Once your bank account is linked to online banking in QBO, we retrieve as much of your transaction data as possible. The amount of data we can fetch when you first connect an account depends on your bank and typically covers a period of 30 to 90 days. If you need to import data that precedes this period, you'll have to export it from your bank first and then import it into your QBO account.

As for the file types supported for import in QBO, you can only upload transactions from a CSV or Quicken (QFX) file. If your file is in a different format, you can use an online converter to change it to a CSV or Quicken (QFX) file.

Once your file is ready, here's how to manually upload your transactions:

1. In the left menu, click Transactions and go to the Bank transactions tab.
2. Choose the blue tile for the account you want to upload the transactions into.
3. Select the Link account▼ dropdown, then select Upload from file. Note: If your account is not connected yet to online banking, select Upload from file.
4. Choose Drag and drop or select files and select the file you downloaded from your bank. Then, select Continue.
5. In the QuickBooks account▼ dropdown, select the account you want to upload the transactions into. Then, select Continue.
6. Follow the onscreen steps to match the columns on the file with the correct fields in QuickBooks. Then select Continue.
7. Select the transactions you like to import. Then select Continue.
8. Select Yes then, Done.
