Not to worry!  The IRS is extremely busy this week. 

The IRS may take up to a week to update your return status.

If for any reason, there is an issue, the IRS will notify you by mail.

You can always call them.  1-800-829-1040

The IRS states the you should receive your refund in 21 days from the date the return is accepted by the IRS.

It is not unusual for your deposit date to be later than expected.  The IRS site says if you haven't received your deposit after 5 days AFTER expected deposit date, then contact them.
