Hi there,
Log into your bank’s website and download your transaction history from the beginning of the year.
Use QBO format if they have it.
If they don’t have this format then export to a CSV file.
Then go to the Banking area in QBO, click the drop-down arrow next to ‘Update’ and choose ‘File Upload’.
