Answer: Home Depot does not offer soil testing. Usually you can get a comprehensive soil test from your local university. Unfortunately, University of Illinois no longer offers soil testing but they do recommend submitting a sample to
University of Wisconsin ? Soil Lab
Soil and Plant Analysis Lab

Visit their website and request a soil test kit. You'll get complete directions plus a list of fees. I'd go with the standard lawn and garden test.
Best wishes with your garden!
