This is the Credit for Taxes Paid to Another State tax form, on the sC1040TC Wksht line 1 (Gross Income) the Turbo Tax program adds the South Carolina Subtractions line 42 from Non-Res Schedule instead of subtracting it from the total gross income. These are subtractions, not additions and make the total gross income more than it actually is, which makes for a significant difference in tax owed.
This is clearly an error in the program, and I had to spend a lot of time determining what went wrong - not what I expected when I purchased both Turbo Tax and an additional State Tax form.
I have to manually enter the correct amount, but I'm not even sure what will happen when I file, or what other issues there are in the program. I would like to know what Turbo Tax intends to do to correct this.
