There is a sort of limit on the two wage earner credit - the instructions say to calculate the earned income to each spouse, take the lesser and limit it to $50,000 before multiplying by .007 to calculate the credit.
See the Worksheet on page 33 in the SC Income Tax Booklet for 2024.

As you are likely aware, the two Wage Earner credit is only for a married couple who both have earned income - see pp 32-33 in the South Carolina Tax Booklet.
So did you enter a type of earned income for the 1099-Ks?
