Explanations of the calculations of certain parts of the return appear at the end of the section.
For instance, when you finish entering a W-2 form, there is an explanation of the refund/ tax due so far. If you review the W-2 form again, you will see that screen again.
To review past sections, use the left side menu to navigate back to the area you want to review. Then click Continue through the section until you get to the explanation page.
Watch for the Explain why links as you do this. They appear in blue on certain pages throughout the return.
