Turbotax is incorrectly calculating my federal tax refund for 2020

Married, filing jointly. In 2019, we owed roughly $2000 in federal tax (12% bracket). In 2020, we had the same income (mostly interest + dividend income) but now Turbotax says we only owe $350 total. 

 

I made quarterly estimated tax payments in 2020 and Turbotax is giving us a refund of $1688. That is too much I think.  When I do the federal review, Turbotax does not find any errors.

 

I am using the windows CD version of Premier.

 

Any suggestions, anyone?
