Should the SC addback of the extra $1500 st. deduct. from the federal OBBB be included in both the resident and nonresident SC forms. It only shows on the resident form

[drmsbm]

I enter all the same information for both the South Carolina resident and non-resident forms (comparing which is most favorable for my situation), but Turbotax is only including the $1500 additional standard deduction amount from the OBBB on the resident return, and not in the non-resident return. This appears to be a Turbotax issue.

Please clarify why you are comparing a South Carolina resident and non-resident return.

SC allows one to use a resident or nonresident return as a part-year resident, depending on which is the most beneficial.  I do not think this is relevant to the apparent issue, however.

If you have an addback issue with SC1040, you might have a look also at the addback for SC state income tax to be sure it's not adding it back twice. Take a look at lines 1(a) through 1(e), you may find the state income tax added back in both lines 1(a) and also buried in line 1(e)...

the SC return is not adding back twice….easy to see when comparing federal to SC sate taxable income amounts, with the difference being $1500.

I think you just need to have a specialist look at the situation I described with a standard verification file TT used testing accuracy of an SC return.

It's true that South Carolina will allow you to file as a resident or non-resident if you lived in the start for part of the year.  However, the tax treatment of resident and Non-resident SC returns are very different from one another.

When filing as a resident of South Carolina, the addbacks for the differences in the itemized deduction and the state addbacks are on page 1 of SC 1040.  If you file as a non-resident, this part of the SC 1040 is blank because the income determination and addbacks of Standard and itemized deductions occur on Schedule NR near line 46.  I have a test case open in the download version of TurboTax that is figuring the South Carolina deductions and addbacks correctly.
