Get your taxes done using TurboTax

Almost a similar question. So I came to the US for the first time in August 2015 and now it's 2020. So does it means that I have completed my 5 years in the US and thus have to file Form 1040 instead of Form 1040 NR-EZ? Does the year 2015 also count as a tax year for me?

For the last 3 years, I have been filling with Form 1040 NR-EZ. So should I apply with Form 1040 for my Tax return 2019?
