Hello, @tracyagardner.
Allow me to provide some information of setting up your partner equity account on Chart of Accounts.
Yes you're correct. You'll need to create a parent account followed by a sub account so you can track your investment.
Also, to create another sub-account is able to tracks when a partner in business withdraw money from the company account. This sub-account can trace each time the partner invests funds into the company and the total amount of the partner’s investment.
In QuickBooks Online, you can set up owners or partners to follow what they can give to your business
You can check to this article for additional information about adding a multiple equity accounts: Add an owner or partner to your books.
For future reference, you may use a Balance Sheet Comparison report in case you want to pull out a report of equity.
Fill me in if you have other questions or concerns. I'd love to help.
