Can I claim the amount I paid in taxes in 2016 and if so, where?

Do you mean estimated 2016 to the IRS?  Or state income taxes paid over and above witholdings

I mean the amount of Fed tax I paid in2015

To enter estimated 2016 taxes that you previously paid to the IRS:

Click Federal Taxes (top menu)

Click Deductions & Credits (just below top menu)

Scroll down to Estimates and Other Taxes Paid and click Show More

Click Start next to Estimates

To enter STATE taxes paid in 2016 (not including W2 and 1099 withholdings, which are already accounted for):

Click Federal Taxes (top menu)

Click Deductions & Credits (just below top menu)

Scroll down to Estimates and Other Taxes Paid and click Show More

Click Start next to Other Income Taxes

Hope this helps.
