Since Congress passed an extension of the deduction in the budget they passed in Feb 2018 retroactive to 2017, my answer is now incorrect. The VA funding fee is once again deductible for 2017.
However, it will be at least 2-4 weeks for the IRS to reprogram their computers and allow tax software companies to turn the deduction back on. So you can wait for the program to be updated, or file without the deduction and amend later to claim it.
