I'm trying to complete Form T1198 for the 2024 tax year and trying to enter the year 2024 as the year of retroactive lump sum payment but it doesn't allow me?

I received a letter from my employer (Ontario Public Service) which represents Form T1198 (Statement of Qualifying Retroactive Lump Sum Payment) confirming that I received a lump sum in 2024 which is included in my total employment income in my T4 representing an arbitration award for the years 2022, 2023, and 2024. I'm trying to complete Form T1198 in the 2024 Turbotax software but it won't allow me to enter the year "2024" as the year of payment. It looks like the form in this software hasn't been updated and finalized yet? Is that true?
