How do I see how Turbo Tax calculate line 72 on form 540?

[KTS2]

I entered $3000 as estimated state tax paid in 2023. TT entered a larger amount, $4000, on line 72 of form 540.  State Board sent me a letter saying $4000 is incorrect and reduced that to $3500. Apparently I missed something when I entered $3000. How do I see how Turbo Tax came up with $4000 for line 72?

Thanks!

Mystery solved!

First mystery. $1000 from 2022 tax refund was applied to 2023 estimated tax. I sent in another $2000 in 2023. I entered $1000 and $2000 as total estimated tax payments for 2023. TT added another $1000 as it remembered that it had applied $1000 from 2022 tax refund. So TT entered $4000 on line 72.

Second mystery. So total estimated tax payment should be only $3000, but State Board said $3500. My fault. I forgot I made another payment of $500!

Anyway, it will be nice if TT reminds me tax refund applied from previous year is automatically included, and I do not have to enter it again.

Thanks!
