The INFO1 through INFO15 cell references are drawn from Invoice Information from the window select button. For example:

If you click on NewViews > Account > Accounts Receivable > Your Customer (Blue Table) > A particular Invoice (green table), the tan table below may show the details of the invoice. Click the window select button on the tan table and choose Invoice Information. Here are your 15 information slots/cell references for this particular invoice.

If you are working in a Sales Journal (NewViews > Sales > Sales Invoices) click on the appropriate Invoice and on the tan table below, click on the window select button and choose Invoice Information. The value on each line is what will be printed on the invoice if the INFO cell reference is defined in the Excel template.

The name column text can be defined globally in Sale Invoices if you click on the window select button (pink table which shows transactions explorer) and select Invoice Information.
