If you used Online TurboTax for 2024, you'll need a PDF of your 2024 return that includes all the worksheets. One of the worksheets is called "Charitable Contributions Summary" that would have a list of your cash and non-cash contributions as well as any contribution carryovers to 2025 (if you have any.)
This time of year is normally a limbo period for getting an online 2024 PDF since TurboTax folks are archiving the files, and the PDFs are normally temporarily unavailable while they undergo that process. You can look to see if you can get it yet (mine is not visible yet.) To do that, log in and go the Tax Home (it may open there.) On the Tax Home page scroll down to the section "Your Tax Returns & Documents", and see if 2024 is listed among the tax years.
