You should provide some guidance/warning to TurboTax users concerning using the std deduction for federal and defaulting to the same for state w/o checking into matters at their state. For example, the std deduction for a married couple filing jointly (fedl) is $24,400 + $1300 each (27,000); and in the State of Alabama, the std deduction for a married couple filing jointly is $4,000.
So if that couple had $20,000 in deductible expenses, and chose to take std deduction on federal return by simply skipping all the deductions and leaving them blank .... by default, they will be adding an additional $16,000 taxable income to their state return ($20,000 - $4,000).
In other words. although in this example TT accurately credits $27,000 as the standard deduction on the federal return ... one might be expecting it to do the same on the state return but it is limited to the respective state revenue law.
BOTTOM LINE: I STRONGLY RECOMMEND YOU CAUTION FOLKS TO BEWARE BEFORE THEY DELETE THE DEMOGRAPHIC DETAILS ABOUT THEIR CHARITABLE CONTRIBUTIONS AND OTHER DEDUCTIBLE ITEMS!!
This is serious!
