I’m trying to figure out what my tax liability is and how I should enter it in

The tax software will figure that out for you.   Enter all of your information.

HOW MUCH IS MY REFUND?  DO I OWE?

No one else can see your screen, your tax return or your account. But YOU can see it.

 Line 34 is a refund

Line 37 is tax due that you have to pay to the IRS by April 15, 2021
