The "standard deduction" is separate from either foreign tax subtractions.
So you can file jointly with your spouse and if you are not reporting a lot of itemized deductions (mortgage interest, sales taxes, medical expenses, etc.) you will get the standard deduction that applies for all taxpayers using the married filing jointly status ($12,600 for TY16).
You would separately claim a foreign tax credit or deduction for foreign taxes:
Go to Federal>Deductions&Credits> Estimated and Other Taxes Paid
Under "Estimated and Other Taxes Paid, choose "Foreign Taxes".
