This should be equity that shows up on the balance sheet. You will go to chart of accounts and set up a new account with account type equity. If payments are still being made for purchase of another company, you will need to also create a liability account.
Do not enter Acquisition of another company if it is not purchased under current company name legally. Also if there are multiple owners and only one owner name is on that company, contact an accountant to handle, do not run through current company.
