I’d be glad to guide walk you through the steps on how to import your bank statement in QuickBooks Online (QBO).
QuickBooks lets you upload your statement using a CSV file. You can either choose the 3 column or 4 column format when importing the file.
The 3 column format has a Date, Description, and Amount column. While the 4 column format has a Date, Description, Credit and Debit column. I’ve attached a screenshot below for your visual reference.
