HOW TO FORCE ITEMIZED DEDUCTIONS

If you want to skip entering your itemized deductions you can do that.  Many people will not have enough itemized deductions this year to itemize, and will just be getting their new higher standard deduction.  The thing is, though, that some of those deductions could make a difference on a state return even if they do not affect your federal return.  Information flows from your federal return to your state return, so it might not be a bad idea to go ahead and enter them anyhow.  It cannot hurt you.

 

The following states allow you to itemize deductions on just the state return: Alabama, Arizona, Arkansas, California, Delaware, Hawaii, Idaho, Iowa, Kentucky, Minnesota, Mississippi, Montana, New York, North Carolina, Oregon, and Wisconsin, 

The online software still won't let me do as those instructions say to do. I want to force itemized deductions, which are a lot higher than standard. Even if it results in the same amount of tax refund, I want the itemized deductions to carry over to next year. 

Itemized deductions do not carry over to the next tax year.   You either have enough to use them for this tax year or you do not, in which case you get the standard deduction.
