Deductions & credits

Now I'm even more confused.  I'm asking about the discrepancy between 2 numbers posted for married filing jointly, the standard deduction.  You said the same thing I've seen online, and TT shows a higher number.  Is TT right or wrong?  FYI I'm 66, my spouse is UNDER 65.  The '+' thing I'm unfamiliar with.

 

Thanks!
