Hello there, @WYO_BOOKS. I'm here to make sure that you can bring your lost bank feed transactions to QuickBooks Desktop (QBDT).
As long as your bank account is operational, you can connect to it again. After this process, you'll have to delete any duplicate transactions to avoid messing up your books.
Also, check out this article if you want to proceed with uploading your transactions manually. Please note that the only accepted file format when importing is a .QBO file. Simply go to the Import Web Connect (.qbo) files section: Set up bank accounts for Bank Feeds in QBDT.
In addition to this, you might need this article when matching transactions in your bank feed: Add and match Bank Feed transactions. Then, make sure to review your accounts to match your statement. Please read this article for your reference: Reconcile an account.
