My 2016 state tax return was audited and determined that I owed more tax that year, but I was only notified of the tax owed in 2019, which paid in December of 2019. What is the correct way to report this payment if (a) I itemize in 2019, or (b) I take the standard deduction. I don't know which way I will end up going, but probably (a). I did itemize my deductions in 2016.
