You can manually upload the transactions through the Imports tab. Let me guide you how:
- From the Gear icon, select Imports.
- Select Import older transactions.
- Select Browse and find the file you downloaded from your bank.
- Click the file and select Open to start the import.
- Review the column headers and data.
- Select Continue to complete the import.
