NC Part time resident trouble with SS being taxed

I moved from Texas to NC on May 22, 2024.  On the Part-Year Resident Income Allocations page, the federal income showes $31,810 of taxable SS benefits.  Interpolating for the NC portion of the year yields $31,810 x .61 = $19,404.  I enter this in the column for "North Carolina Resident income" for the row "Taxable SS Benefits".

 

When I do this my "NC Tax Due" increases from $1200 to $1900 dollars.  So it appears to be taxing the SS benefits.  But NC doesn't tax SS benefits so the "NC Tax Due" should not increase.

 

When I go to the next screen "Part-Year Resident Income Allocations", it again shows me that the Federal Adustments were $31,810.  I enter $19,404 again in "North Carolina Resident Adjustments, but the "NC Tax Due" does not change.  I thought this might be where turbotax removes the SS benfits from being taxed in NC.

 

How do I enter the SS benefit info for these screens so that the "NC Tax Due" reflects no SS benefits and goes back to $1200?
