Yes you enter everything on the federal side. One reason is because state estimated payments can be a federal itemized deduction. There is a separate spot for state payments and you gave to pick the right state. It will flow over to the state return.
To enter Federal or State Estimated Taxes Paid, including a state estimated payment made in January for the prior year, go to
Federal on left or at top (Personal for Home & Business)
Deductions and Credits
Then scroll way down to Estimates and Other Taxes Paid
Estimated Taxes - click the start button
Federal Estimated payments should be on 1040 line 26.
You enter state estimated payments under the federal side (because they can be a federal itemized Deduction). THEN after you finish filling out the estimates under Federal you need to click on the State Tab at the top and start the state return over for it to update.
