After you file
If you transferred your 2024 return into 2025, on the Income/Deductions topic pages, you should see your 2024 amounts next to your 2025 amounts. TurboTax prompts with 'Needs Review' for any topics you haven't visited in 2025 that appeared on your 2024 return. You'll also see a comparison between years in the Review section.
You can compare PDFs for each year side by side for more detail.
