Can I import 2023 Turbotax information into my 2024 return preparations for comparative purposes?

Only if you Transfer 2023 before you start 2024.  So you would have to clear 20124 and start over to Transfer.   Do you have the .tax2023 file from last year?   Are you using the Online version?  If you started 2024 in the same account it should have automatically transferred 2023.  You can transfer 2023 but doing this will also clear out all your current entries. If you haven't filed, registered or paid you can try to clear and start over
