The VA funding fee is a type of mortgage insurance. It is fully deductible in the year you closed (you aren't clear if you closed in 2016 or 2017). It is deductible if you are under the income limit for deductiing mortgage insurance.
It should be listed in box 5 of the 1098 from your mortgage lender. If it is not, you can add it to box 5 when you enter the 1098.
If you closed in December and made no payments in 2016 and don't get a 1098, create a lender in the name of the closing bank, say "I didn't get a 1098 for this lender" and enter the VA funding fee as mortgage insurance that way.
