PTE tax

Hi , I have an S-Corp, and I would like to elect for PTE tax, for year 2024 tax return (not for tax return 2023) should I elect  it for along with 2023 tax return when it will be filed before March 15 2024.

And as I read its the instruction, the first payment will be June 15, 2024? am I right?

So, I will take this credit on 2024 tax return which will be filed before March 2025, is it correct?

Thanks for your help
