Can I purchase worker's comp insurance through Intuit?

Maybe. There is an option to try but it is either not available in all states or for all work categories (I tried several years ago to get a quote and came up empty)

UNder Employees and Workers Compensation is an option to "Set Up a New WC Payment Service" which will allow you to submit info for a quote.  Get local quotes to compare, though. It might not be any bargain
