Hello jenny Mc1, thanks for reaching out to the Community
In QuickBooks Self-Employed, it's recommended that the bank feed remains connected (some connection messages mean that the history will be deleted).
In most cases, we can recover all transactions to the newly connected account (or to the default Cash account) as previously categorised, meaning you won't have to re-do any work.
From checking, I can see that your case is in the hands of a member of our support team, who will continue to work towards restoring the lost transactions for you.
If you do require any additional support, please feel free to get back in touch below!
