My federal tax return (single) has itemized deductions. In reviewing the SC state addback worksheet, TurboTax is adding back the difference between my itemized deduction and the standard federal deduction (which is correct and appears on line 1a on my SC1040 form), but also appears to be adding "State and local tax addback" on line 1e "Other additions to income" which appears to be the difference between my itemized deduction amount in my federal return and $10,000. I don't know why it is doing this and I think it is wrong.
If I change my federal return to the standard deduction, on my SC1040 form, line 1a goes to zero, which is correct, but line 1e now populates as $750. I don't know where this number comes from. I can not change what TurboTax puts on line 1e in either situation.
I think this is an error and needs to be corrected. I filed with the standard deduction in 2024 and my SC state return had nothing populated on line 1a or 1e.
