I'm showing an error importing a csv file says failed probably our fault try again

Thanks for visiting us here with your concern, williams5038. I'll share insights to ensure you'll able to import .csv files into your QuickBooks Self-Employed account.

When importing CSV files into QBSE, let's ensure all details are in the correct format to enable your file to upload in QuickBooks. 

We can create three or four-column layouts of a CSV file for your data. You can refer to this article to be more guided about the file format: Format CSV files in excel to get bank transactions into QuickBooks. Also, it contains detailed information on modifying them if you'll receive an error message when uploading.

Moreover, I'm adding this reference to guide you in reviewing and organizing your income and expenses: Categorize transactions in QuickBooks Self-Employed. It includes additional steps on how to create and manage category rules.

You can always get back into this thread if you have additional queries about importing transactions in QBSE. We'd be delighted to assist you again. Keep safe and have a good one!
