Hello there, @Almise.

In QuickBooks Self-Employed (QBSE), we can manually upload the transactions.

Here's how:

1. Go to the Transaction menu.
2. Select Add Transaction.
3. Enter the amount and a description.
4. Click the Select a category menu, then choose the best category to organize your transaction.
5. If you have a receipt, you can drag and drop it onto the form.
6. Click Save.
7. Repeat the process until everything has been added.

For more information, visit this article: Add older transactions to QuickBooks Self-Employed.
