Hey there, Crestone.
Thanks for reaching out for support here in the Community. I want to make sure you're able to get your bank information into QuickBooks Online.
This can be done manually through what is referred to as a WebConnect. The first step in this process is to download your bank transactions as one of the following formats:
The downloaded file can then be uploaded into QuickBooks by:
1. Clicking the Banking tab in the left navigation bar.
2. Select the black drop-down arrow beside of Update, and select File upload.
This article offers more information on this type of setup: https://quickbooks.intuit.com/community/Banking-and-bank-feeds/How-to-upload-more-than-90-days-of-bank-transactions/m-p/187501.
Additionally, this write-up covers the how-to's of importing using a .CSV file: https://quickbooks.intuit.com/community/Banking-and-bank-feeds/How-to-import-bank-transactions-using-Excel-CSV-files/m-p/185578.
Keep up the great work and please let me know if you have any other questions. I'll be here to help any way that I can.
