Why pay $45 for audit defense for state tax filing when none is needed or required for federal filing?

The filing for CA state taxes requires $45 audit defense added to CA filing of $15 according to TurboTax billing.  Printing the state taxes is about $10, postal costs of $15 for sending the tax return to Sacramento for a total of $25.  Why should I pay TurboTax $60 for digitally filing my state taxes?
