Hello, tyraus.
You might consider using an account type cash and cash equivalents account instead of Owner's Equity. This will allow you to use this account when recording a BAS payment in the QBO GST menu.
If there are transactions that are already recorded in the Equity account, you transfer them manually to your new account. It’d be best as well to check your accountant about the right accounts that you can use in this process.
Stay in touch if you have other questions related to QuickBooks.
