Get your taxes done using TurboTax

Yes, you should be able to enter the estimated tax payments paid in the screen called "How much did you pay in federal estimated taxes?" The 4 estimated payment due dates are already populated in the screen.  All you have to enter is the amount of payment made by each due date.

Since I do not see a blue teardrop beneath these payment fields, you may need to revisit the location where you tried to enter the payments and correct.
