Standard deduction recommended but is half the amount of last year's itemized deduction?

I have a very similar income and expense structure from this year to last.  This year though I get a "congratulations the standard deduction (married filing jointly) is the best option for you" message, but in comparison with last year I had $51K in deductions using the itemized approach.  I see that the individual exemption is gone, but is there some other reason why Turbo Tax wouldn't recommend itemizing given my expenses are relatively the same as last year?  Thanks in advance for the help.  I'll have a whopper of a bill to pay if this I really should take the standard deduction...2018deduct.png
