Yes, you are right and the total tax amount cannot be $2 in your case. However, the amount could be attributable to the difference you need to pay after your withholdings and credits were calculated, not the tax liability.  

Line 15 (Taxable Income) is $24,092.  Line 16 (Tax) is $2.  Any credits are picked up later.  For me $4,400 for estimated tax payments (line 26).  There is no way I can file this return and I've paid for it.  I don't know what to do now.  This looks like a calculation error to me.

That could be an error.

You might create a diagnostic copy and  we will look at it.
Click on tax tools in the left menu bar, then Tools, then Share my file with an agent, which will create a diagnostic copy.

Keep in mind that diagnostic copies wipe out your personal information such as names, SSNs, addresses, etc.  Only numbers tied into calculations and numbers inputted are shown.  This is something the agent does with you over the phone if you are in need of figuring out specific errors.

The Diagnostic copy was created, please advise.
