You should just hold tight to wait for the IRS information request or release of your refund. They will honor the direct deposit that was requested by you assuming your refund stays the same. This is the usual protocol and rarely do they deviate from it unless the return is changed for some reason.
As you indicated, your return was a random selection, so no reason for concern. When the deposit comes, if you requested the Refund Processing Service where your fees should be withheld, that will still take place.
If for some reason the refund is not received then you will be notified. All the details are provided in the TurboTax article below.
