Retirement Savings Contribution Credit

My friend was employed as a teacher at 2 different charter schools in 2019, and had a combined AGI of $29608, after her elective deferrals of $5040 to the employer retirement plans. $1680 was deferred to the first employer which was listed on her W-2 box 12 as Code E – Elective deferrals under section 403(b) salary reduction agreement – and Turbo Tax assigned $168 to the Retirement Savings Contribution Credit. $3360 was deferred in retirement contribution to her 2nd employer and it was coded on the W-2 box 12 as Code G – Elective deferrals and employer contributions to a section 457(b) deferred compensation plan. Turbo Tax did not assign any Retirement savings Credit although she would have been eligible for up to $32 additional amt. to meet the $200 maximum credit allowed for Single Fling status (10% up to $2000 contribution.) W-2 for 1st employer has box 13 for retirement plan checked, but W-2 of 2nd employer did not have a check mark in box 13.

Does the 457(b) plan from the 2nd employer somehow not qualify for this credit?
