Ah ok, sorry I understand now. What you would need to do is go into the bank management section in Quick File and recreate those 5 bank accounts. When you click on the settings (the orange cog) for each you will see a nominal code for that account. When you import your TB you should then be able to map each bank balance to the corresponding bank nominal code on Quick File.
If the TB has been imported then you could either remove the TB journal and re-import it or create a new journal to distribute the balances from the default account (1200) to the respective accounts you added earlier.
