Hey Gladys,
Cheers on making the upgrade! It's a big milestone, and it ensures you'll be able to take advantage of the great features and refinements of the most current version. The upgrade is meant to be quick and painless, so I'd really like to take a deeper look at your account to get to the bottom of this.
If you prefer to start from scratch and enter your opening balances, that's certainly an option. Your accountant is the best person to help you with that. Check out our Find an Accountant page to find a QuickBooks pro in your area. You can enter in your postal code to find accountants near you, and filter for the product you're using.
Otherwise, please reach out for some real-time assistance with a trained agent. These agents are great help in these situations and have the ability to use screen share sessions and other tools to help resolve your issues. You can read about our support policies here: Intuit QuickBooks Desktop software support policies.
Don't be afraid to reach out! I want to make sure this gets fixed early on.
