If both my spouse and I paid quarterly estimated state taxes, how do we accurately represent it in Turbo Tax? Is there a way to differentiate the payments for me and her?

Are you filing a Joint return?  Why did you pay the estimates separately?  You only need to pick the state to enter them.  If you paid more than 4 estimates you can add more rows.

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 - click the Start or Update button
