You can go back into TurboTax and get the Federal Estimated Tax Payments.
Go to Federal Taxes tab,
Then Other Tax Situations
scroll down to Other Tax Forms and the 3rd one in that group is W-4 and Estimated Taxes.
You may have just skipped by this area when doing your taxes.
If you are already finished with the taxes, sometimes it is difficult to get back into the program right away. If you encounter that, just click on "add another state" to let you back in, you will not actually add the state, this just lets you back in the program if you have just filed the return.
