This year deductions are changing and several will be limited. There is a max 10,000 limit of State, local, property, and sales tax (SALT) deduction. And employee job expenses have been suspended. You can only deduct Medical/Dental that's over 7.5% of your AGI.

Deductions that have been suspended for 2018

Because of the new law passed in Dec 2017, if you bought a house after Dec 15 2017, you can only deduct the interest on the first 750K of your primary home, but if you bought the house before that date, you can deduct interest on up to 1M of the loan (Married filing jointly). In my case, the TT automatically used $0 for mortgage interest because I missed the little box in TT that said Adjusted Mortgage interest = 0. So essentially it disregarded my close to $31k in mortgage interest and ended up choosing Standard deduction instead. You have to do some manual math to figure out the 'average' loan balance for the year and divide 1M by that amount to find the proration % of the mortgage interest. Apply that % and then enter the number in the Adjusted Mortgage Interest box (instead of the 0 defaulted by genius TT). Voila, now TT will use the new interest amount and use Itemized deduction instead of Standard. At least this was the problem in my case. Hope that helps
