Recheck your entries on the carryover page in the Adoption Credit topic. There should only be an entry in the 2021 box for 9K since that is what is unused from that adoption year. There would not be a 2022 entry since no adoption expenses were incurred during that year.
Then look at your form 8839 either in "Forms Mode" for desktop or print/download for online. Line 12 should be zero, lines 13 and 14 should each show the 9K carryover. Line 15 will show your credit limit. Line 16 will be the lower of 15 or 14. If 15 is lower then the difference is carryover to 2024.
In 2024 again you only enter that carryover amount into the 2021 tax year box as no adoption expenses were added in 2022 or 2023.
