CA 540 Schedule P line 9 showing strange number

[mattlohry]

In reviewing the forms generated by TurboTax for my California state return, I noticed that there is a small ($4) entry in line 9 of CA 540 schedule P (AMT & Credit Limitations) which I don't understand. According to the instructions for this form, this line is to enter adjustments to gain or loss that result from a different basis being required for AMT. However, I am not in such a situation (all my gains and losses from 2019 are the result of stock sales for which the basis should be the same in AMT and regular tax). Why is TurboTax entering a value here?

it may have been something that had carried over from previous years.  Who knows!! in the meantime, since it is a insignificant amount, just ignore it because this is something that is not going to seriously impact your return.

Dave,

Thanks for the response. I doubt that it was a past year carry-over, since I didn't make any basis adjustments in the CA return for earlier years, as far as I know.

That said, I agree that the number is small and doesn't impact the return in any significant way; I just wanted to make sure that there wasn't anything fishy going on in the back-end calculations. TurboTax does a good job giving details about this in many other places, just not here for some reason. Is there some way to lift-the-hood on this number? The usual 'Data Source' option in the Form View right-click menu is greyed-out.

If it is grayed-out then this is not easy to remove.  You might contact phone support as they have the ability to troubleshoot to see if that can be removed. i have actually participated in these types of troubleshoots and sometimes they are not easy to diagnose.  This was the reason why i suggested to ignore it in the first place only because this will not seriously impact your taxes.

It is reporting $8800 owed when it should be $0.  The amended return is not completing the Sch P.

The post that described the case in details is the following. I don't how to link them so I copy it here:

TurboTax put large negative and positive numbers +-(15 digits of 9s) in Sch P, p1-2 for CA State Return

I am using TurboTax Business for 2023. Both 1041 and NY State passed error checks without any issue. However, error check for CA State found too large or too small errors: After importing 1041 data into CA State, TT puts large negative and positive numbers +-(15 digits of 9s) in line 12, 13 of Sch P, p1-2. You only can override them, but still cause error.  I have contacted TT Tech Support and spoke to 4 specialists but no solution.

My TT Business, NY State, CA State are up-to-date. My Windows 10 Pro is also up-to-date.

Researches lead me think it could be a bug in TT Business program for CA State, since it failed to treat negative numbers as zero for some entries when it should, which also messed up the calculations thereafter.
