My eligibility period is from May 8, 2013 to May 8, 2018. It says in 12b, "Tell us when you filed your income taxes in the last 5 years using the chart.." The years indicated there are 2017, 2016, 2015, 2014 which I said "Yes" to both Required to file and Taxes filed. Should I also put 2013 and I say "No" to both Required to file and Taxes filed?
