Homeschooling Rate in the US

Hello,

Working on a project to find homeschooling rate in the US, but to no success. Does anyone know how to find detail data of homeschool rate in the US? I'm looking to analyze Homeschool rate in the US, children in household ages 6 to 17.

I found an article in the US Census website with the following info. "In the first week (April 23-May 5) of Phase 1 of the Household Pulse Survey  about 5.4% of U.S. households with school-aged children reported homeschooling." 

However, I can find data that would give me the 5.4%

Thank you!
