If my taxes have already been accepted how do i go back and show the estimated state taxes i paid in 2016 for my 2017 taxes?

Last year i was asked if i wanted to use my 2016 state taxes to pay estimated taxes for 2017, which i did. I have already done my taxes this year and it has been accepted, however i did not include the estimated taxes i paid in 2016 (was not asked about it when going through all the steps, i assumed since ive done my taxes with TT every year they would transfer that information as well). My estimated tax payment was not included and now i owe the state. Im not sure how to correct this as my returns have already been accepted. I do not itemize any deductions? My taxes are simple with 1 dependant but i knew i would make more money in 2017
