The "refund monitor" is not meaningful until you have entered all of your information. With only one W-2 entered your income might appear low enough that you wouldn't owe any tax, so you would get back all the tax that was withheld. See what happens after you enter the rest of your W-2s.

If you're asking about the rounding, everything on a tax return is rounded to whole dollars. The $1,022.82 tax withheld becomes $1,023.
