Completed return and am getting a refund though I had no deductions from income throughout the year

There are some credits you can get.  Like the Recovery Rebate Credit on line 30.  But be careful.  Line 30 is only if you didn't get the full 3rd Stimulus payment or qualify for more.   So if you got the 3rd 1,400 Stimulus payment during the year make sure line 30 is Blank.
