I itemized in 2017. However, my state tax refund does not show up on my 1040. I'm assuming that would be because turbo tax thinks I took the standard deduction last year.

What do I need to do to note that I itemized last year?

You can enter your state and local tax refunds from 2017 in the following location: 

1.) Wages and Income

2.) Other Common Income

3.) Refunds Received for State/Local Tax Returns

At the end of this section, TurboTax will ask you if you itemized last year and will determine if this entry is taxable.
