Solo 401K won't pass review to e-file, failed in Keogh, SEP and SIMPLE Contribution Worksheet

[mx99]

for Solo 401k of single owner C-Corp, my W2 box 12 has 30000 (D). So in TT, I entered elective deferral 22500 and catchup 7500 as I'm over 50, with employer contribution 10000. Next, I entered adjustment amount 40000, everything looks good going thru the rest.
But TT failed in review, I cannot e-file, it asks to "Check This Entry" of "Keogh, SEP and SIMPLE Contribution Worksheet"  line 6c, should NOT > 7500

I don't understand what's wrong here. 

Any help is appreciated.
