How is the "Federal Tax Due" amount calculated?

I'm talking about the running number in the upper left of the screen that shows your tax due or refund at any particular time while you're doing your taxes.  My specific problem is this: I'm unable to enter mortgage deductions yet since the form is not ready.  For purposes of the "Federal Tax Due" number, is Turbotax using my 2017 number (which for some reason is wildly inaccurate), or the 2018 number (which for some reason has a number that I never entered)?
