The comparison typically appears once you reach the "Review" phase of your return.
Navigate to the Review tab in the left-hand menu (or use the "Review" button at the top).
Continue through the review screens until you see a section titled "Let's review your numbers" or "Bottom Line."
Look for a link or button labeled Year-Over-Year Comparison.
If it isn't immediately visible, look at the very bottom of the Detailed Tax Summary page.
If you are using the installed software, you have a more direct way to see it:
Switch to Forms Mode (usually a button in the top right or bottom left).
In the list of forms on the left, search for "Two-Year Comp" or "Tax History."
This will pull up a side-by-side table of every line item from last year vs. this year.
The year-over-year comparison only shows the current tax year and the previous tax year.
Also be aware that the year-over-year comparison is only available if you transferred you previous year return into your current year return.
