Need advice on liquidating some of my Wealthfront account to purchase GOOGL/AMZN.

As the title reads I'm thinking about liquidating some or all of my Wealthfront funds and transfer them to my TD Ameritrade account in order to
purchase 5 shares of each so I can do covered calls after the stock splits. I'm on the fence about this because of the tax implications from selling.

Any advice, experience, concerns would be great.
