did these clients get transferred into 2024 recently or earlier in December or early January?   

Early transfers have been known to have issues with stuff missing, if these were transferred in early, do you have a client that you have NOT worked on yet, that you could delete and retransfer now to see if its still happening?

I only have 2 clients with 114's, I just transferred one of them into 2024 and all the 114 info IS included.  So I think you may have jumped the gun when you transferred client into 2024, I find it best to wait as long into January as possible before transferring any clients.  I only pull my dummy/tester files over and my own return to fiddle with until later in January.

If a newly transferred one still has the issue, Id advise to delete the client in 2024, open 2023 and run an Update, then go back to 2024 and transfer it in again.  Corp basis info wasnt transferring over until an additional update on 2023 had been run, it could be a similar problem.
