You don't enter the 30% value yourself...at least not how you appear to think.
You enter the total value of the appreciated stock in the Charitable Donations section....indicating that it was a stock as you start the entry as a Donation.
Then the tax software will do the limitation calculation, based on what total income you have entered up until that point. And it will re-calculate the 30% limitation itself as you add in more income.
BUT, the 2024 software is still being worked on and is not completed yet....so I have no idea if that section is working properly yet. Should be OK by late January of 2025, so I wouldn't necessarily trust anything entered now.
2023 desktop software works OK for those types of donations, so 2024 should do so too, eventually, if it isn't doing so yet.
