The IRS is allowing a $300 per person above the line deduction for charitable donations if you do not itemize. This would be $600 for a married filing joint return. So that you can get the above-the-line charitable deduction, enter the donations under Deductions and Credits. When you get towards the end of the return and get ready to e-file, TurboTax will ask you if you want to claim the $300/$600 for charitable donations. Enter either the $300/$600 depending on your filing status.
