QBI eligibility after 3 years

I am a software engineer - working for the same company since 1992.  In 2018 I was switched from a company employee to a contractor. I have received a 1099-NEC for the past 4 years.  The supplied help for QBI eligibility states that a contractor in my situation is not eligible for the QBI deduction for 3 years. Am I eligible for the QBI deduction now that I have been a contractor for more than 3 years?
