It provided hours of entertainment!
I was an INTJ - I have always been almost 50/50 T and F.
So you are a good example of the 'unscientific nature' of MBTI.
Theoretically, you would be a really strong T, with Sensing as your Third Function, so your N vs. S 'should be' the one to be 50/50.
It's worth a read of the INTP type description and see if it fit you overall any better than INTJ. Which strength feels 'strongest and most private' - the N or the T? If it's the N, you may well be a P, although not as strong a P as your DH. Lots of Moms adopt J habits because if they don't the family will fall apart.
Alternatively, you could
be a very Strong T, but because your really are a J, T is your first strength, which as a good Introvert you keep it 'close to the vest.' Throw in the 'socialized as a female' factor, and that could account for your scoring, It may be that your T is very strong indeed, but you have learned to also use the socially preferred for females F strength.
Just for curiosity - are you 'good at S' when you need to be, or is lack of S at the bottom of most of your missteps in life?
And it may just plain be that the poor theory has reached the end of it's predictive powers. I was on a pretty good role there for a while.
