I know the importance of retrieving cleared transactions, Rob1973. Let me help you recover lost transactions in QuickBooks Self-Employed (QBSE).

If the bank is removed from the Banking section, it clears the downloaded transactions from your financial institution.

We can manually import the bank statements into your QuickBooks Self-Employed account to recover lost entries.

1. Go to Settings and select Imports.
2. Choose Import older transactions for the account you want to add transactions to.
3. Follow the onscreen steps to upload the CSV file.
4. Review the column headers and data. Map the Date, Description, and Amount columns on the CSV file.
5. Then, tap Continue to complete the import.

Moreover, categorizing transactions manually from your online bank in QBSE is essential. It ensures that the system accurately places them on the relevant line of your Schedule C form. Refer to this article: Categorise transactions in QuickBooks Self-Employed.
