You will enter state estimated payments on the federal return. For each payment made, you will indicate the date and the state that you paid it to. Estimated payments will then flow to the appropriate lines on each of the state returns.
State income tax returns can vary considerably from one state to another. TurboTax will put your estimated payments on the correct lines for each state that you file. The estimated taxes will be calculated when determining the amount of refund or the amount to be paid.
Individuals that make multi state estimated payments are relatively rare. Most people working in multiple states are W2 employees and their state taxes are withheld from their pay and recorded on their W2 form.
