Get your taxes done using TurboTax

Hello.  This is confusing as the description say that it does not impact your deductions however it does dramatically which not only increases the federal cost but also increase the AGI so the State return is higher.  If I have $50K in deductions and the a -$25K in state and local taxes greater than $10K, my totals deductions are reduced to $25K vs what they were n 2017 which included everything.  Can this be correct and the same regardless of where you live?
