No, you will not be able to deduct your 2016 donations in 2017. However, you can amend your 2016 return for free and if you will get a refund you can mail in, if you will not get a refund then you do not have to amend. If you would like to see how adding the donations to 2016 amended return will change your refund, please use the TurboTax FAQ below to get started.
