STEP TWO: Enter the beginning account balances. Click the + New button at the upper left-hand corner of the screen. Choose Journal Entry under the Other column. Enter Journal Entry #1 with the date of 1/1/2021. The journal entry appears below. Under Description, type Beginning Balance. For Accounts Receivable and Accounts Payable, you will need to fill in the Name column. For Accounts Receivable, click Add New from the drop-down menu in the Name column. Enter A Customer as the name and choose Customer as the type. Click Save. For Accounts Payable, click Add New from the drop-down menu in the Name column. Enter A Vendor as the name and choose Vendor as the type. Click Save.

I did this part but was wondering what to do with the chart - do I put all those in as journal entries?

For example

Journal entry 1

Accounts receivable 13000

Service Revenue 13000
