I am transferring my bookkeeping to quickbooks. How do I record the opening balances from the balance sheet?

You should run the Trial Balance and use it as opening balance for each account.

If you have to open a new QBO account, make sure to click the Buy button to get the discounted price for up to 6 months. If you purchase from the trial account, you have to pay the regular price.
