How can I find out what I entered for miles driven and personal mileage that I filled out on my 2021 taxes?

You can go back to your TurboTax return and take a look. If you used TurboTax Online, you can find your returns at: https://ww2.2021.turbotaxonline.intuit.ca/

If you used TurboTax CD/Download, then the returns would be stored on your computer. The default location that TurboTax uses is Documents>TurboTax>2021
