TurboTax has not resolved this. I calculate my Itemized Deductions to be $25,629 but TT has it as $26,021. TT error is in the calculation of paid taxes. Difference $392

I traced this discrepancy back to the first section of Sched A - paid taxes - state income, local real estate, + pers property taxes.  For me its the addition of 3 numbers. TT number is $392 higher than my calculation. I cannot find the source of this discrepancy in TT.  Can anyone help?

UPDATE:  Solved!  The $392 was what I owed and paid of 2017 State Income tax.

Did you have a state tax liability on your 2017 tax return. If so, TT figures that payment, made in Spring 2018, into the calculation.

Solved.  I was also going to say to check your W2 for anything in boxes 14 and 19 like for SDI or VDI.
