Hi penningmeester-e,
Thank you for reaching out to Community for support and assistance with your bank transactions. Our QuickBooks Online Development Team have resolved the connection issue affecting access to several Financial Institutions over the weekend and earlier today. I suggest clearing cache on your browser and login to your QuickBooks Online account to ensure you're able to update your transactions at this time. I'd be happy to guide you through uploading them manually, should you encounter any issues moving forward.
To avoid uploading duplicate transactions, I recommend reviewing the account history and make note of the date of the last transaction in the account. You'll then login to your bank's website and follow the instructions to download the file in csv format, based on the date you've noted. Open and review the spreadsheet to ensure it's in the correct format prior to uploading it into QuickBooks Online.
Follow these steps to upload your transactions:
1. In QuickBooks Online, go to the Banking or Transactions menu. Then select the Banking tab
2. Click the blue tile for the account you want to upload the transactions into
3. Select the ▼ dropdown beside Link account and Upload from file
4. Hit Browse and then select the csv file you downloaded from your bank
5. From the Account ▼ dropdown, choose the account to upload the transactions into
6. Follow the onscreen steps to match the columns on the file with the correct fields in QuickBooks and hit Next
7. Select the transactions to import and continue
8. When you're ready, hit Let's go.
Here's an article for manually uploading transactions into QuickBooks Online for your reference.
Here's how to delete any duplicate entries:
1. From the left menu, click on Banking or Transactions
2. In the For Review tab, select the duplicate transactions
3. Click on Exclude
4. When complete, click on the Excluded tab, select al entries
5. Hit Delete
Please feel free to ask any other questions. We'd be glad to help!
