Actually, if KPERS is form a state pickup under section 414(h) of the US Code, that portion should not be included in the after-tax total. That would be indication for state-tax purposes and would already have been included for federal purposes in box 12. I'm not familiar enough with KPERS to be sure.
[Edit] KPERS appears to be 401(a) plan, not a state pickup indication, so it may already be included in the 401(a) amount listed in box 14.
