If you're using TurboTax Desktop and saved a PDF copy of your return, look for Form 8283.
If you're using TurboTax Online, you can also save a PDF of your return and look at the detail on this form. However, if you didn't, open TurboTax, scroll to the bottom of the page, and click on 'Add a State'. This will get you back into your return where you can view your entries, and also save a PDF copy of your return.
